Industrial automation controller project online/offline state separation

ABSTRACT

An industrial integrated development environment (IDE) comprises a development interface that affords a user a great deal of control over the editing tools, workspace canvases, and project information rendered at a given time. The industrial IDE system also includes various graphical features that assist the user to easily discern the various online and offline states of industrial control programs developed using the IDE system. Collaboration tools supported by the IDE system facilitate communicative and coordinated editing of control programs by multiple developers, and the IDE system conveys the resulting online and offline states of these programs using intuitive graphical indicators.

DETAILED DESCRIPTION

The subject disclosure is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the subject disclosure can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof.

As used in this application, the terms “component,” “system,” “platform,” “layer,” “controller,” “terminal,” “station,” “node,” “interface” are intended to refer to a computer-related entity or an entity related to, or that is part of, an operational apparatus with one or more specific functionalities, wherein such entities can be either hardware, a combination of hardware and software, software, or software in execution. For example, a component can be, but is not limited to being, a process running on a processor, a processor, a hard disk drive, multiple storage drives (of optical or magnetic storage medium) including affixed (e.g., screwed or bolted) or removable affixed solid-state storage drives; an object; an executable; a thread of execution; a computer-executable program, and/or a computer. By way of illustration, both an application running on a server and the server can be a component. One or more components can reside within a process and/or thread of execution, and a component can be localized on one computer and/or distributed between two or more computers. Also, components as described herein can execute from various computer readable storage media having various data structures stored thereon. The components may communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems via the signal). As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry which is operated by a software or a firmware application executed by a processor, wherein the processor can be internal or external to the apparatus and executes at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components without mechanical parts, the electronic components can include a processor therein to execute software or firmware that provides at least in part the functionality of the electronic components. As further yet another example, interface(s) can include input/output (I/O) components as well as associated processor, application, or Application Programming Interface (API) components. While the foregoing examples are directed to aspects of a component, the exemplified aspects or features also apply to a system, platform, interface, layer, controller, terminal, and the like.

As used herein, the terms “to infer” and “inference” refer generally to the process of reasoning about or inferring states of the system, environment, and/or user from a set of observations as captured via events and/or data. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. The inference can be probabilistic—that is, the computation of a probability distribution over states of interest based on a consideration of data and events. Inference can also refer to techniques employed for composing higher-level events from a set of events and/or data. Such inference results in the construction of new events or actions from a set of observed events and/or stored event data, whether or not the events are correlated in close temporal proximity, and whether the events and data come from one or several event and data sources.

In addition, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from the context, the phrase “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, the phrase “X employs A or B” is satisfied by any of the following instances: X employs A; X employs B; or X employs both A and B. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from the context to be directed to a singular form.

Furthermore, the term “set” as employed herein excludes the empty set; e.g., the set with no elements therein. Thus, a “set” in the subject disclosure includes one or more elements or entities. As an illustration, a set of controllers includes one or more controllers; a set of data resources includes one or more data resources; etc. Likewise, the term “group” as utilized herein refers to a collection of one or more entities; e.g., a group of nodes refers to one or more nodes.

Various aspects or features will be presented in terms of systems that may include a number of devices, components, modules, and the like. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc. and/or may not include all of the devices, components, modules etc. discussed in connection with the figures. A combination of these approaches also can be used.

FIG. 1 is a block diagram of an example industrial control environment 100. In this example, a number of industrial controllers 118 are deployed throughout an industrial plant environment to monitor and control respective industrial systems or processes relating to product manufacture, machining, motion control, batch processing, material handling, or other such industrial functions. Industrial controllers 118 typically execute respective control programs to facilitate monitoring and control of industrial devices 120 making up the controlled industrial assets or systems (e.g., industrial machines). One or more industrial controllers 118 may also comprise a soft controller executed on a personal computer or other hardware platform, or on a cloud platform. Some hybrid devices may also combine controller functionality with other functions (e.g., visualization). The control programs executed by industrial controllers 118 can comprise substantially any type of code capable of processing input signals read from the industrial devices 120 and controlling output signals generated by the industrial controllers 118, including but not limited to ladder logic, sequential function charts, function block diagrams, or structured text.

Industrial devices 120 may include both input devices that provide data relating to the controlled industrial systems to the industrial controllers 118, and output devices that respond to control signals generated by the industrial controllers 118 to control aspects of the industrial systems. Example input devices can include telemetry devices (e.g., temperature sensors, flow meters, level sensors, pressure sensors, etc.), manual operator control devices (e.g., push buttons, selector switches, etc.), safety monitoring devices (e.g., safety mats, safety pull cords, light curtains, etc.), and other such devices. Output devices may include motor drives, pneumatic actuators, signaling devices, robot control inputs, valves, pumps, and the like.

Industrial controllers 118 may communicatively interface with industrial devices 120 over hardwired or networked connections. For example, industrial controllers 118 can be equipped with native hardwired inputs and outputs that communicate with the industrial devices 120 to effect control of the devices. The native controller I/O can include digital I/O that transmits and receives discrete voltage signals to and from the field devices, or analog I/O that transmits and receives analog voltage or current signals to and from the devices. The controller I/O can communicate with a controller's processor over a backplane such that the digital and analog signals can be read into and controlled by the control programs. Industrial controllers 118 can also communicate with industrial devices 120 over a network using, for example, a communication module or an integrated networking port. Exemplary networks can include the Internet, intranets, Ethernet, DeviceNet, ControlNet, Data Highway and Data Highway Plus (DH/DH+), Remote I/O, Fieldbus, Modbus, Profibus, wireless networks, serial protocols, and the like. The industrial controllers 118 can also store persisted data values that can be referenced by their associated control programs and used for control decisions, including but not limited to measured or calculated values representing operational states of a controlled machine or process (e.g., tank levels, positions, alarms, etc.) or captured time series data that is collected during operation of the automation system (e.g., status information for multiple points in time, diagnostic occurrences, etc.). Similarly, some intelligent devices—including but not limited to motor drives, instruments, or condition monitoring modules—may store data values that are used for control and/or to visualize states of operation. Such devices may also capture time-series data or events on a log for later retrieval and viewing.

Industrial automation systems often include one or more human-machine interfaces (HMIs) 114 that allow plant personnel to view telemetry and status data associated with the automation systems, and to control some aspects of system operation. HMIs 114 may communicate with one or more of the industrial controllers 118 over a plant network 116, and exchange data with the industrial controllers to facilitate visualization of information relating to the controlled industrial processes on one or more pre-developed operator interface screens. HMIs 114 can also be configured to allow operators to submit data to specified data tags or memory addresses of the industrial controllers 118, thereby providing a means for operators to issue commands to the controlled systems (e.g., cycle start commands, device actuation commands, etc.), to modify setpoint values, etc. HMIs 114 can generate one or more display screens through which the operator interacts with the industrial controllers 118, and thereby with the controlled processes and/or systems. Example display screens can visualize present states of industrial systems or their associated devices using graphical representations of the processes that display metered or calculated values, employ color or position animations based on state, render alarm notifications, or employ other such techniques for presenting relevant data to the operator. Data presented in this manner is read from industrial controllers 118 by HMIs 114 and presented on one or more of the display screens according to display formats chosen by the HMI developer. HMIs may comprise fixed location or mobile devices with either user-installed or pre-installed operating systems, and either user-installed or pre-installed graphical application software.

Some industrial environments may also include other systems or devices relating to specific aspects of the controlled industrial systems. These may include, for example, a data historian 110 that aggregates and stores production information collected from the industrial controllers 118 or other data sources, device documentation stores containing electronic documentation for the various industrial devices making up the controlled industrial systems, inventory tracking systems, work order management systems, repositories for machine or process drawings and documentation, vendor product documentation storage, vendor knowledgebases, internal knowledgebases, work scheduling applications, or other such systems, some or all of which may reside on an office network 108 of the industrial environment.

Higher-level systems 126 may carry out functions that are less directly related to control of the industrial automation systems on the plant floor, and instead are directed to long term planning, high-level supervisory control, analytics, reporting, or other such high-level functions. These systems 126 may reside on the office network 108 at an external location relative to the plant facility, or on a cloud platform with access to the office and/or plant networks. Higher-level systems 126 may include, but are not limited to, cloud storage and analysis systems, big data analysis systems, manufacturing execution systems, data lakes, reporting systems, etc. In some scenarios, applications running at these higher levels of the enterprise may be configured to analyze control system operational data, and the results of this analysis may be fed back to an operator at the control system or directly to a controller 118 or device 120 in the control system.

The various control, monitoring, and analytical devices that make up an industrial environment must be programmed or configured using respective configuration applications specific to each device. For example, industrial controllers 118 are typically configured and programmed using a control programming development application such as a ladder logic editor (e.g., executing on a client device 124). Using such development platforms, a designer can write control programming (e.g., ladder logic, structured text, function block diagrams, etc.) for carrying out a desired industrial sequence or process and download the resulting program files to the controller 118. Separately, developers design visualization screens and associated navigation structures for HMIs 114 using an HMI development platform (e.g., executing on client device 122) and download the resulting visualization files to the HMI 114. Some industrial devices 120—such as motor drives, telemetry devices, safety input devices, etc.—may also require configuration using separate device configuration tools (e.g., executing on client device 128) that are specific to the device being configured. Such device configuration tools may be used to set device parameters or operating modes (e.g., high/low limits, output signal formats, scale factors, energy consumption modes, etc.).

The necessity of using separate configuration tools to program and configure disparate aspects of an industrial automation system results in a piecemeal design approach whereby different but related or overlapping aspects of an automation system are designed, configured, and programmed separately on different development environments. For example, a motion control system may require an industrial controller to be programmed and a control loop to be tuned using a control logic programming platform, a motor drive to be configured using another configuration platform, and an associated HMI to be programmed using a visualization development platform. Related peripheral systems—such as vision systems, safety systems, etc.—may also require configuration using separate programming or development applications.

This segregated development approach can also necessitate considerable testing and debugging efforts to ensure proper integration of the separately configured system aspects. In this regard, intended data interfacing or coordinated actions between the different system aspects may require significant debugging due to a failure to properly coordinate disparate programming efforts.

Industrial development platforms are also limited in terms of the development interfaces offered to the user to facilitate programming and configuration. These interfaces typically offer a fixed user experience that requires the user to develop control code, visualizations, or other control system aspects using a relatively fixed set of development interfaces. In many development scenarios, the number of editing options—e.g., function buttons or other selectable editing controls, configuration fields, etc.—that are displayed on the development platform's interface exceed the number required by the developer for a current project development task, resulting in an unnecessarily cluttered development workspace and rendering it difficult to locate a desired editing option.

To address at least some of these or other issues, one or more embodiments described herein provide an integrated development environment (IDE) for designing, programming, and configuring multiple aspects of an industrial automation system using a common design environment and data model. Embodiments of the industrial IDE can be used to configure and manage automation system devices in a common way, facilitating integrated, multi-discipline programming of control, visualization, and other aspects of the control system.

In some embodiments, the development interface rendered by the IDE system can afford the user a great deal of control over the editing tools, workspace canvases, and project information rendered at a given time. The IDE system also automatically filters the tools, panels, and information available for selection based on a determination of the current project development task being carried out by the user, such that a focused subset of editing tools relevant to a current development task are made available for selection while other tools are hidden. The development interface also allows the user to selectively render or hide selected tools or information from among the relevant, filtered set of tools. This approach can reduce or eliminate unnecessary clutter and assist the developer in quickly and easily locating and selecting a desired editing function. The IDE's development interface can also conform to a structured organization of workspace canvases and panels that facilitates intuitive workflow.

FIG. 2 is a block diagram of an example integrated development environment (IDE) system 202 according to one or more embodiments of this disclosure. Aspects of the systems, apparatuses, or processes explained in this disclosure can constitute machine-executable components embodied within machine(s), e.g., embodied in one or more computer-readable mediums (or media) associated with one or more machines. Such components, when executed by one or more machines, e.g., computer(s), computing device(s), automation device(s), virtual machine(s), etc., can cause the machine(s) to perform the operations described.

IDE system 202 can include a user interface component 204 including an IDE editor 224, a project generation component 206, a project deployment component 208, a collaboration management component 210, one or more processors 218, and memory 220. In various embodiments, one or more of the user interface component 204, project generation component 206, project deployment component 208, collaboration management component 210, the one or more processors 218, and memory 220 can be electrically and/or communicatively coupled to one another to perform one or more of the functions of the IDE system 202. In some embodiments, components 204, 206, 208, and 210 can comprise software instructions stored on memory 220 and executed by processor(s) 218. IDE system 202 may also interact with other hardware and/or software components not depicted in FIG. 2 . For example, processor(s) 218 may interact with one or more external user interface devices, such as a keyboard, a mouse, a display monitor, a touchscreen, or other such interface devices.

User interface component 204 can be configured to receive user input and to render output to the user in any suitable format (e.g., visual, audio, tactile, etc.). In some embodiments, user interface component 204 can be configured to communicatively interface with an IDE client that executes on a client device (e.g., a laptop computer, tablet computer, smart phone, etc.) that is communicatively connected to the IDE system 202 (e.g., via a hardwired or wireless connection). The user interface component 204 can then receive user input data and render output data via the IDE client. In other embodiments, user interface component 314 can be configured to generate and serve development interface screens to a client device (e.g., program development screens), and exchange data via these interface screens. As will be described in more detail herein, the development interfaces rendered by the user interface component 204 support a number of user experience features that simplify project development workflow, reduce stress associated with an overcluttered development workspace, and assist developers to locate desired editing functions more quickly and easily. Input data that can be received via various embodiments of user interface component 204 can include, but is not limited to, programming code, industrial design specifications or goals, engineering drawings, AR/VR input, DSL definitions, video or image data, or other such input. Output data rendered by various embodiments of user interface component 204 can include program code, programming feedback (e.g., error and highlighting, coding suggestions, etc.), programming and visualization development screens, etc.

Project generation component 206 can be configured to create a system project comprising one or more project files based on design input received via the user interface component 204, as well as industrial knowledge, predefined code modules and visualizations, and automation objects 222 maintained by the IDE system 202. Project deployment component 208 can be configured to commission the system project created by the project generation component 206 to appropriate industrial devices (e.g., controllers, HMI terminals, motor drives, AR/VR systems, etc.) for execution. To this end, project deployment component 208 can identify the appropriate target devices to which respective portions of the system project should be sent for execution, translate these respective portions to formats understandable by the target devices, and deploy the translated project components to their corresponding devices. Collaboration management component 210 can be configured to manage and regulate design input submitted by multiple developers in a manner that ensures project consistency and coordination between developers.

The one or more processors 218 can perform one or more of the functions described herein with reference to the systems and/or methods disclosed. Memory 220 can be a computer-readable storage medium storing computer-executable instructions and/or information for performing the functions described herein with reference to the systems and/or methods disclosed.

FIG. 3 is a diagram illustrating a generalized architecture of the industrial IDE system 202 according to one or more embodiments. Industrial IDE system 202 can implement a common set of services and workflows spanning not only design, but also commissioning, operation, and maintenance. In terms of design, the IDE system 202 can support not only industrial controller programming and HMI development, but also sizing and selection of system components, device/system configuration, AR/VR visualizations, and other features. The IDE system 202 can also include tools that simplify and automate commissioning of the resulting project and assist with subsequent administration of the deployed system during runtime.

Embodiments of the IDE system 202 that are implemented on a cloud platform also facilitate collaborative project development whereby multiple developers 304 contribute design and programming input to a common automation system project 302. Collaborative tools supported by the IDE system can manage design contributions from the multiple contributors and perform version control of the aggregate system project 302 to ensure project consistency.

Based on design and programming input from one or more developers 304, IDE system 202 generates a system project 302 comprising one or more project files. The system project 302 encodes one or more of control programming; HMI, AR, and/or VR visualizations; device or sub-system configuration data (e.g., drive parameters, vision system configurations, telemetry device parameters, safety zone definitions, etc.); or other such aspects of an industrial automation system being designed. IDE system 202 can identify the appropriate target devices 306 on which respective aspects of the system project 302 should be executed (e.g., industrial controllers, HMI terminals, variable frequency drives, safety devices, etc.), translate the system project 302 to executable files that can be executed on the respective target devices, and deploy the executable files to their corresponding target devices 306 for execution, thereby commissioning the system project 302 to the plant floor for implementation of the automation project.

To support enhanced development capabilities, some embodiments of IDE system 202 can be built on an object-based data model rather than a tag-based architecture. Automation objects 222 serve as the building block for this object-based development architecture. FIG. 4 is a diagram illustrating several example automation object properties that can be leveraged by the IDE system 202 in connection with building, deploying, and executing a system project 302. Automation objects 222 can be created and augmented during design, integrated into larger data models, and consumed during runtime. These automation objects 222 provide a common data structure across the IDE system 202 and can be stored in an object library (e.g., part of memory 220) for reuse. The object library can store predefined automation objects 222 representing various classifications of real-world industrial assets 402, including but not limited to pumps, tanks, values, motors, motor drives (e.g., variable frequency drives), industrial robots, actuators (e.g., pneumatic or hydraulic actuators), or other such assets. Automation objects 222 can represent elements at substantially any level of an industrial enterprise, including individual devices, machines made up of many industrial devices and components (some of which may be associated with their own automation objects 222), and entire production lines or process control systems.

An automation object 222 for a given type of industrial asset can encode such aspects as 2D or 3D visualizations, alarms, control coding (e.g., logic or other type of control programming), analytics, startup procedures, testing protocols, validation reports, simulations, schematics, security protocols, and other such properties associated with the industrial asset 402 represented by the object 222. Automation objects 222 can also be geotagged with location information identifying the location of the associated asset. During runtime of the system project 302, the automation object 222 corresponding to a given real-world asset 402 can also record status or operational history data for the asset. In general, automation objects 222 serve as programmatic representations of their corresponding industrial assets 402, and can be incorporated into a system project 302 as elements of control code, a 2D or 3D visualization, a knowledgebase or maintenance guidance system for the industrial assets, or other such aspects.

FIG. 5 is a diagram illustrating example data flows associated with creation of a system project 302 for an automation system being designed using IDE system 202 according to one or more embodiments. A client device 504 (e.g., a laptop computer, tablet computer, desktop computer, mobile device, wearable AR/VR appliance, etc.) executing an IDE client application 514 can access the IDE system's project development tools and leverage these tools to create a comprehensive system project 302 for an automation system being developed. Through interaction with the system's user interface component 204, developers can submit design input 512 to the IDE system 202 in various supported formats, including industry-specific control programming (e.g., control logic, structured text, sequential function charts, etc.) and HMI screen configuration input. Based on this design input 512 and information stored in an industry knowledgebase (predefined code modules 508 and visualizations 510, guardrail templates 506, physics-based rules 516, etc.), user interface component 204 renders design feedback 518 designed to assist the developer in connection with developing a system project 302 for configuration, control, and visualization of an industrial automation system.

In addition to control programming and visualization definitions, some embodiments of IDE system 202 can be configured to receive digital engineering drawings (e.g., computer-aided design (CAD) files) as design input 512. In such embodiments, project generation component 206 can generate portions of the system project 302—e.g., by automatically generating control and/or visualization code—based on analysis of existing design drawings. Drawings that can be submitted as design input 512 can include, but are not limited to, P&ID drawings, mechanical drawings, flow diagrams, or other such documents. For example, a P&ID drawing can be imported into the IDE system 202, and project generation component 206 can identify elements (e.g., tanks, pumps, etc.) and relationships therebetween conveyed by the drawings. Project generation component 206 can associate or map elements identified in the drawings with appropriate automation objects 222 corresponding to these elements (e.g., tanks, pumps, etc.) and add these automation objects 222 to the system project 302. The device-specific and asset-specific automation objects 222 include suitable code and visualizations to be associated with the elements identified in the drawings. In general, the IDE system 202 can examine one or more different types of drawings (mechanical, electrical, piping, etc.) to determine relationships between devices, machines, and/or assets (including identifying common elements across different drawings) and intelligently associate these elements with appropriate automation objects 222, code modules 508, and/or visualizations 510. The IDE system 202 can leverage physics-based rules 516 as well as pre-defined code modules 508 and visualizations 510 as necessary in connection with generating code or project data for system project 302.

The IDE system 202 can also determine whether pre-defined visualization content is available for any of the objects discovered in the drawings and generate appropriate HMI screens or AR/VR content for the discovered objects based on these pre-defined visualizations. To this end, the IDE system 202 can store industry-specific, asset-specific, and/or application-specific visualizations 510 that can be accessed by the project generation component 206 as needed. These visualizations 510 can be classified according to industry or industrial vertical (e.g., automotive, food and drug, oil and gas, pharmaceutical, etc.), type of industrial asset (e.g., a type of machine or industrial device), a type of industrial application (e.g., batch processing, flow control, web tension control, sheet metal stamping, water treatment, etc.), or other such categories. Predefined visualizations 510 can comprise visualizations in a variety of formats, including but not limited to HMI screens or windows, mashups that aggregate data from multiple pre-specified sources, AR overlays, VR objects representing 3D virtualizations of the associated industrial asset, or other such visualization formats. IDE system 202 can select a suitable visualization for a given object based on a predefined association between the object type and the visualization content.

In another example, markings applied to an engineering drawing by a user can be understood by some embodiments of the project generation component 206 to convey a specific design intention or parameter. For example, a marking in red pen can be understood to indicate a safety zone, two circles connected by a dashed line can be interpreted as a gearing relationship, and a bold line may indicate a camming relationship. In this way, a designer can sketch out design goals on an existing drawing in a manner that can be understood and leveraged by the IDE system 202 to generate code and visualizations. In another example, the project generation component 206 can learn permissives and interlocks (e.g., valves and their associated states) that serve as necessary preconditions for starting a machine based on analysis of the user's CAD drawings. Project generation component 206 can generate any suitable code (ladder logic, function blocks, etc.), device configurations, and visualizations based on analysis of these drawings and markings for incorporation into system project 302. In some embodiments, user interface component 204 can include design tools for developing engineering drawings within the IDE platform itself, and the project generation component 206 can generate this code as a background process as the user is creating the drawings for a new project. In some embodiments, project generation component 206 can also translate state machine drawings to a corresponding programming sequence, yielding at least skeletal code that can be enhanced by the developer with additional programming details as needed.

Also, or in addition, some embodiments of IDE system 202 can support goal-based automated programming. For example, the user interface component 204 can allow the user to specify production goals for an automation system being designed (e.g., specifying that a bottling plant being designed must be capable of producing at least 5000 bottles per second during normal operation) and any other relevant design constraints applied to the design project (e.g., budget limitations, available floor space, available control cabinet space, etc.). Based on this information, the project generation component 206 will generate portions of the system project 302 to satisfy the specified design goals and constraints. Portions of the system project 302 that can be generated in this manner can include, but are not limited to, device and equipment selections (e.g., definitions of how many pumps, controllers, stations, conveyors, drives, or other assets will be needed to satisfy the specified goal), associated device configurations (e.g., tuning parameters, network settings, drive parameters, etc.), control coding, or HMI screens suitable for visualizing the automation system being designed.

Some embodiments of the project generation component 206 can also generate at least some of the project code for system project 302 based on knowledge of parts that have been ordered for the project being developed. This can involve accessing the customer's account information maintained by an equipment vendor to identify devices that have been purchased for the project. Based on this information the project generation component 206 can add appropriate automation objects 222 and associated code modules 508 corresponding to the purchased assets, thereby providing a starting point for project development.

Some embodiments of project generation component 206 can also monitor customer-specific design approaches for commonly programmed functions (e.g., pumping applications, batch processes, palletizing operations, etc.) and generate recommendations for design modules (e.g., code modules 508, visualizations 510, etc.) that the user may wish to incorporate into a current design project based on an inference of the designer's goals and learned approaches to achieving the goal. To this end, some embodiments of project generation component 206 can be configured to monitor design input 512 over time and, based on this monitoring, learn correlations between certain design actions (e.g., addition of certain code modules or snippets to design projects, selection of certain visualizations, etc.) and types of industrial assets, industrial sequences, or industrial processes being designed. Project generation component 206 can record these learned correlations and generate recommendations during subsequent project development sessions based on these correlations. For example, if project generation component 206 determines, based on analysis of design input 512, that a designer is currently developing a control project involving a type of industrial equipment that has been programmed and/or visualized in the past in a repeated, predictable manner, the project generation component 206 can instruct user interface component 204 to render recommended development steps or code modules 508 the designer may wish to incorporate into the system project 302 based on how this equipment was configured and/or programmed in the past.

In some embodiments, IDE system 202 can also store and implement guardrail templates 506 that define design guardrails intended to ensure the project's compliance with internal or external design standards. Based on design parameters defined by one or more selected guardrail templates 506, user interface component 204 can provide, as a subset of design feedback 518, dynamic recommendations or other types of feedback designed to guide the developer in a manner that ensures compliance of the system project 302 with internal or external requirements or standards (e.g., certifications such as TUV certification, in-house design standards, industry-specific or vertical-specific design standards, etc.). This feedback 518 can take the form of text-based recommendations (e.g., recommendations to rewrite an indicated portion of control code to comply with a defined programming standard), syntax highlighting, error highlighting, auto-completion of code snippets, or other such formats. In this way, IDE system 202 can customize design feedback 518—including programming recommendations, recommendations of predefined code modules 508 or visualizations 510, error and syntax highlighting, etc.—in accordance with the type of industrial system being developed and any applicable in-house design standards.

Guardrail templates 506 can also be designed to maintain compliance with global best practices applicable to control programming or other aspects of project development. For example, user interface component 204 may generate and render an alert if a developer's control programing is deemed to be too complex as defined by criteria specified by one or more guardrail templates 506. Since different verticals (e.g., automotive, pharmaceutical, oil and gas, food and drug, marine, etc.) must adhere to different standards and certifications, the IDE system 202 can maintain a library of guardrail templates 506 for different internal and external standards and certifications, including customized user-specific guardrail templates 506. These guardrail templates 506 can be classified according to industrial vertical, type of industrial application, plant facility (in the case of custom in-house guardrail templates 506) or other such categories. During development, project generation component 206 can select and apply a subset of guardrail templates 506 determined to be relevant to the project currently being developed, based on a determination of such aspects as the industrial vertical to which the project relates, the type of industrial application being programmed (e.g., flow control, web tension control, a certain batch process, etc.), or other such aspects. Project generation component 206 can leverage guardrail templates 506 to implement rules-based programming, whereby programming feedback (a subset of design feedback 518) such as dynamic intelligent autocorrection, type-aheads, or coding suggestions are rendered based on encoded industry expertise and best practices (e.g., identifying inefficiencies in code being developed and recommending appropriate corrections).

Users can also run their own internal guardrail templates 506 against code provided by outside vendors (e.g., OEMs) to ensure that this code complies with in-house programming standards. In such scenarios, vendor-provided code can be submitted to the IDE system 202, and project generation component 206 can analyze this code in view of in-house coding standards specified by one or more custom guardrail templates 506. Based on results of this analysis, user interface component 204 can indicate portions of the vendor-provided code (e.g., using highlights, overlaid text, etc.) that do not conform to the programming standards set forth by the guardrail templates 506, and display suggestions for modifying the code in order to bring the code into compliance. As an alternative or in addition to recommending these modifications, some embodiments of project generation component 206 can be configured to automatically modify the code in accordance with the recommendations to bring the code into conformance.

In making coding suggestions as part of design feedback 518, project generation component 206 can invoke selected code modules 508 stored in a code module database (e.g., on memory 220). These code modules 508 comprise standardized coding segments for controlling common industrial tasks or applications (e.g., palletizing, flow control, web tension control, pick-and-place applications, conveyor control, etc.). In some embodiments, code modules 508 can be categorized according to one or more of an industrial vertical (e.g., automotive, food and drug, oil and gas, textiles, marine, pharmaceutical, etc.), an industrial application, or a type of machine or device to which the code module 508 is applicable. In some embodiments, project generation component 206 can infer a programmer's current programming task or design goal based on programmatic input being provided by a the programmer (as a subset of design input 512), and determine, based on this task or goal, whether one of the pre-defined code modules 508 may be appropriately added to the control program being developed to achieve the inferred task or goal. For example, project generation component 206 may infer, based on analysis of design input 512, that the programmer is currently developing control code for transferring material from a first tank to another tank, and in response, recommend inclusion of a predefined code module 508 comprising standardized or frequently utilized code for controlling the valves, pumps, or other assets necessary to achieve the material transfer.

Customized guardrail templates 506 can also be defined to capture nuances of a customer site that should be taken into consideration in the project design. For example, a guardrail template 506 could record the fact that the automation system being designed will be installed in a region where power outages are common, and will factor this consideration when generating design feedback 518; e.g., by recommending implementation of backup uninterruptable power supplies and suggesting how these should be incorporated, as well as recommending associated programming or control strategies that take these outages into account.

IDE system 202 can also use guardrail templates 506 to guide user selection of equipment or devices for a given design goal; e.g., based on the industrial vertical, type of control application (e.g., sheet metal stamping, die casting, palletization, conveyor control, web tension control, batch processing, etc.), budgetary constraints for the project, physical constraints at the installation site (e.g., available floor, wall or cabinet space; dimensions of the installation space; etc.), equipment already existing at the site, etc. Some or all of these parameters and constraints can be provided as design input 512, and user interface component 204 can render the equipment recommendations as a subset of design feedback 518. In some embodiments, project generation component 206 can also determine whether some or all existing equipment can be repurposed for the new control system being designed. For example, if a new bottling line is to be added to a production area, there may be an opportunity to leverage existing equipment since some bottling lines already exist. The decision as to which devices and equipment can be reused will affect the design of the new control system. Accordingly, some of the design input 512 provided to the IDE system 202 can include specifics of the customer's existing systems within or near the installation site. In some embodiments, project generation component 206 can apply artificial intelligence (AI) or traditional analytic approaches to this information to determine whether existing equipment specified in design in put 512 can be repurposed or leveraged. Based on results of this analysis, project generation component 206 can generate, as design feedback 518, a list of any new equipment that may need to be purchased based on these decisions.

In some embodiments, IDE system 202 can offer design recommendations based on an understanding of the physical environment within which the automation system being designed will be installed. To this end, information regarding the physical environment can be submitted to the IDE system 202 (as part of design input 512) in the form of 2D or 3D images or video of the plant environment. This environmental information can also be obtained from an existing digital twin of the plant, or by analysis of scanned environmental data obtained by a wearable AR appliance in some embodiments. Project generation component 206 can analyze this image, video, or digital twin data to identify physical elements within the installation area (e.g., walls, girders, safety fences, existing machines and devices, etc.) and physical relationships between these elements. This can include ascertaining distances between machines, lengths of piping runs, locations and distances of wiring harnesses or cable trays, etc. Based on results of this analysis, project generation component 206 can add context to schematics generated as part of system project 302, generate recommendations regarding optimal locations for devices or machines (e.g., recommending a minimum separation between power and data cables), or make other refinements to the system project 302. At least some of this design data can be generated based on physics-based rules 516, which can be referenced by project generation component 206 to determine such physical design specifications as minimum safe distances from hazardous equipment (which may also factor into determining suitable locations for installation of safety devices relative to this equipment, given expected human or vehicle reaction times defined by the physics-based rules 516), material selections capable of withstanding expected loads, piping configurations and tuning for a specified flow control application, wiring gauges suitable for an expected electrical load, minimum distances between signal wiring and electromagnetic field (EMF) sources to ensure negligible electrical interference on data signals, or other such design features that are dependent on physical rules.

In an example use case, relative locations of machines and devices specified by physical environment information submitted to the IDE system 202 can be used by the project generation component 206 to generate design data for an industrial safety system. For example, project generation component 206 can analyze distance measurements between safety equipment and hazardous machines and, based on these measurements, determine suitable placements and configurations of safety devices and associated safety controllers that ensure the machine will shut down within a sufficient safety reaction time to prevent injury (e.g., in the event that a person runs through a light curtain).

In some embodiments, project generation component 206 can also analyze photographic or video data of an existing machine to determine inline mechanical properties such as gearing or camming and factor this information into one or more guardrail templates 506 or design recommendations.

As noted above, the system project 302 generated by IDE system 202 for a given automaton system being designed can be built upon an object-based architecture that uses automation objects 222 as building blocks. FIG. 6 is a diagram illustrating an example system project 302 that incorporates automation objects 222 into the project model. In this example, various automation objects 222 representing analogous industrial devices, systems, or assets of an automation system (e.g., a process, tanks, valves, pumps, etc.) have been incorporated into system project 302 as elements of a larger project data model 602. The project data model 602 also defines hierarchical relationships between these automation objects 222. According to an example relationship, a process automation object representing a batch process may be defined as a parent object to a number of child objects representing devices and equipment that carry out the process, such as tanks, pumps, and valves. Each automation object 222 has associated therewith object properties or attributes specific to its corresponding industrial asset (e.g., those discussed above in connection with FIG. 4 ), including executable control programming for controlling the asset (or for coordinating the actions of the asset with other industrial assets) and visualizations that can be used to render relevant information about the asset during runtime.

At least some of the attributes of each automation object 222 are default properties defined by the IDE system 202 based on encoded industry expertise pertaining to the asset represented by the objects. Other properties can be modified or added by the developer as needed (via design input 512) to customize the object 222 for the particular asset and/or industrial application for which the system projects 302 is being developed. This can include, for example, associating customized control code, HMI screens, AR presentations, or help files associated with selected automation objects 222. In this way, automation objects 222 can be created and augmented as needed during design for consumption or execution by target control devices during runtime.

Once development on a system project 302 has been completed, commissioning tools supported by the IDE system 202 can simplify the process of commissioning the project in the field. When the system project 302 for a given automation system has been completed, the system project 302 can be deployed to one or more target control devices for execution. FIG. 7 is a diagram illustrating commissioning of a system project 302. Project deployment component 208 can compile or otherwise translate a completed system project 302 into one or more executable files or configuration files that can be stored and executed on respective target industrial devices of the automation system (e.g., industrial controllers 118, HMI terminals 114 or other types of visualization systems, motor drives 710, telemetry devices, vision systems, safety relays, etc.).

Conventional control program development platforms require the developer to specify the type of industrial controller (e.g., the controller's model number) on which the control program will run prior to development, thereby binding the control programming to a specified controller. Controller-specific guardrails are then enforced during program development which limit how the program is developed given the capabilities of the selected controller. By contrast, some embodiments of the IDE system 202 can abstract project development from the specific controller type, allowing the designer to develop the system project 302 as a logical representation of the automation system in a manner that is agnostic to where and how the various control aspects of system project 302 will run. Once project development is complete and system project 302 is ready for commissioning, the user can specify (via user interface component 204) target devices on which respective aspects of the system project 302 are to be executed. In response, an allocation engine of the project deployment component 208 will translate aspects of the system project 302 to respective executable files formatted for storage and execution on their respective target devices.

For example, system project 302 may include—among other project aspects—control code, visualization screen definitions, and motor drive parameter definitions. Upon completion of project development, a user can identify which target devices—including an industrial controller 118, an HMI terminal 114, and a motor drive 710—are to execute or receive these respective aspects of the system project 302. Project deployment component 208 can then translate the controller code defined by the system project 302 to a control program file 702 formatted for execution on the specified industrial controller 118 and send this control program file 702 to the controller 118 (e.g., via plant network 116). Similarly, project deployment component 208 can translate the visualization definitions and motor drive parameter definitions to a visualization application 704 and a device configuration file 708, respectively, and deploy these files to their respective target devices for execution and/or device configuration.

In general, project deployment component 208 performs any conversions necessary to allow aspects of system project 302 to execute on the specified devices. Any inherent relationships, handshakes, or data sharing defined in the system project 302 are maintained regardless of how the various elements of the system project 302 are distributed. In this way, embodiments of the IDE system 202 can decouple the project from how and where the project is to be run. This also allows the same system project 302 to be commissioned at different plant facilities having different sets of control equipment. That is, some embodiments of the IDE system 202 can allocate project code to different target devices as a function of the particular devices found on-site. IDE system 202 can also allow some portions of the project file to be commissioned as an emulator or on a cloud-based controller.

As an alternative to having the user specify the target control devices to which the system project 302 is to be deployed, some embodiments of IDE system 202 can actively connect to the plant network 116 and discover available devices, ascertain the control hardware architecture present on the plant floor, infer appropriate target devices for respective executable aspects of system project 302, and deploy the system project 302 to these selected target devices. As part of this commissioning process, IDE system 202 can also connect to remote knowledgebases (e.g., web-based or cloud-based knowledgebases) to determine which discovered devices are out of date or require firmware upgrade to properly execute the system project 302. In this way, the IDE system 202 can serve as a link between device vendors and a customer's plant ecosystem via a trusted connection in the cloud.

Copies of system project 302 can be propagated to multiple plant facilities having varying equipment configurations using smart propagation, whereby the project deployment component 208 intelligently associates project components with the correct industrial asset or control device even if the equipment on-site does not perfectly match the defined target (e.g., if different pump types are found at different sites). For target devices that do not perfectly match the expected asset, project deployment component 208 can calculate the estimated impact of running the system project 302 on non-optimal target equipment and generate warnings or recommendations for mitigating expected deviations from optimal project execution.

As noted above, some embodiments of IDE system 202 can be embodied on a cloud platform. FIG. 8 is a diagram illustrating an example architecture in which cloud-based IDE services 802 are used to develop and deploy industrial applications to a plant environment. In this example, the industrial environment includes one or more industrial controllers 118, HMI terminals 114, motor drives 710, servers 801 running higher level applications (e.g., ERP, MES, etc.), and other such industrial assets. These industrial assets are connected to a plant network 116 (e.g., a common industrial protocol network, an Ethernet/IP network, etc.) that facilitates data exchange between industrial devices on the plant floor. Plant network 116 may be a wired or a wireless network. In the illustrated example, the high-level servers 810 reside on a separate office network 108 that is connected to the plant network 116 (e.g., through a router 808 or other network infrastructure device).

In this example, IDE system 202 resides on a cloud platform 806 and executes as a set of cloud-based IDE service 802 that are accessible to authorized remote client devices 504. Cloud platform 806 can be any infrastructure that allows shared computing services (such as IDE services 802) to be accessed and utilized by cloud-capable devices. Cloud platform 806 can be a public cloud accessible via the Internet by devices 504 having Internet connectivity and appropriate authorizations to utilize the IDE services 802. In some scenarios, cloud platform 806 can be provided by a cloud provider as a platform-as-a-service (PaaS), and the IDE services 802 can reside and execute on the cloud platform 806 as a cloud-based service. In some such configurations, access to the cloud platform 806 and associated IDE services 802 can be provided to customers as a subscription service by an owner of the IDE services 802. Alternatively, cloud platform 806 can be a private cloud operated internally by the industrial enterprise (the owner of the plant facility). An example private cloud platform can comprise a set of servers hosting the IDE services 802 and residing on a corporate network protected by a firewall.

Cloud-based implementations of IDE system 202 can facilitate collaborative development by multiple remote developers who are authorized to access the IDE services 802. When a system project 302 is ready for deployment, the project 302 can be commissioned to the plant facility via a secure connection between the office network 108 or the plant network 116 and the cloud platform 806. As discussed above, the industrial IDE services 802 can translate system project 302 to one or more appropriate executable files—control program files 702, visualization applications 704, device configuration files 708, system configuration files 812—and deploy these files to the appropriate devices in the plant facility to facilitate implementation of the automation project.

FIG. 9 is an example development interface 902 that can be rendered by one or more embodiments of the industrial IDE system's user interface component 204. Development interface 902 is organized into panels and workspaces in a manner to be described in more detail herein and supports automated and manual curation features that declutter the development space and bring a subset of project editing functions that are relevant to a current development task into focus. These features can improve the user's development workflow experience by filtering out selectable options that are not relevant to a current development task, allowing relevant editing tools and information to be located more easily.

The basic structure of development interface 902 comprises a canvas area 930 in which resides a workspace canvas 940 (having an associated tab 932), a global panel control bar 920 on the right-side edge of the interface 902 (to the right of the canvas area 930), a menu bar 904 along the top edge of the interface 902, and a tool bar 906 below the menu bar 904. Other panels can be selectively added or removed from the interface's workspace using visibility control icons on the global panel control bar 920 or via selectable options under the View option of the menu bar 904. These panels can be added to or removed from three main panel area—a left global panel area 922, a bottom global panel area 924, and a right global panel area 928. In the example scenario depicted in FIG. 9 , a Properties panel 936 is visible in the right global panel area 928, and an Explorer panel 910 and a Toolbox panel 912 have been rendered in a vertically stacked arrangement in the left global panel area 922. Development interface 902 can also include a search bar 934 for searching the open project using text string searches. The search bar 934 can also be used for inserting text or initiating a shortcut in some embodiments.

FIG. 10 a is a close-up view of the global panel control bar 920 illustrating an example organization of panel visibility icons. Visibility icons are organized vertically into three groups along the global panel control bar 920, the respective groups residing in a global left panel control area 914, a global right panel control area 916, and a global bottom panel control area 918 of the control bar 920. The three panel control areas are labeled with respective header icons 1002, 1004, and 1006 illustrating which global panel area (left, right, or bottom) are controlled by the associated icons. In the illustrated example, the left panel control area 914 comprises an Explorer visibility icon 1008 that, in response to selection, toggles the visibility of the Explorer panel 910 in the left global panel area 922. The right panel control area 916 comprises three visibility icons 1010 a-1010 c, which control visibility of a Properties panel (visibility icon 1010 a), an Online panel (visibility icon 1010 b), and a Cross Reference panel (visibility icon 1010 c), respectively, in the right global panel area 928. The bottom panel control area 918 comprises two visibility icons 1012 a and 1012 b, which control visibility of an Errors panel (visibility icon 1012 a) and an Output panel (visibility icon 1012 b), respectively, in the bottom global panel area 924.

The visibility icons on global panel control bar 920 can act as toggle buttons that toggle the visibility of their corresponding panels, such that selecting the icon a first time causes the corresponding panel to be rendered in its designated area, and selecting the icon a second time removes its corresponding panel from its designated area. The visibility icons can be color animated such that the color of the icon indicates the visible or hidden state of the corresponding panel (e.g., black for hidden and blue for visible).

FIG. 10 b is an example View menu 1014 that can be rendered as a drop-down menu in response to selection of the View option in the menu bar 904. View menu 1014 renders selectable visibility controls corresponding to, and having the same functionality as, the visibility icons rendered on the global panel control bar 920, allowing the user to selectively render and hide panels using either this menu 1014 or the global panel control bar 920. Similar to the global panel control bar 920, the selectable visibility controls are organized according to Left Panels, Right Panels, and Bottom Panels. Unlike the global panel control bar 920, the selectable controls of the View menu 1014 are rendered as selectable text rather than icons, with checkmarks indicating panels that are currently visible.

In some embodiments, any panels associated with a global panel area (left, right, or bottom) that have been set to be pinned (to be discussed below) can be rendered visible or invisible with a single selection by selecting either the header icon (icon 1002, 1004, or 1006) corresponding to that area in the global panel control bar 920 or the header text for that set of panels (e.g., the Right Panels header 1016) in the View menu 1014.

In some embodiments, the panels whose visibility is controlled from the global panel control bar 920 can be global panels that are relevant to all development tasks or contexts supported by the industrial IDE system 202 (content panels, which are relevant to specific development tasks or contexts, will be described below). In the example depicted in FIGS. 10 a and 10 b , the global panels include an Explorer panel through which a user can browse and select aspects or elements of the automation project, a Properties panel that renders property information for a selected element within canvas area 930, an Online panel that renders communication statistics for the industrial IDE system, a Cross Reference panel that renders cross reference information for a selected element within canvas area 930 (e.g., by listing all usages or instances of the selected element within the industrial automation system project), an Output panel that renders output states, and an Errors panel that lists active and/or historical development or runtime errors. However, any type of global panel can be supported by the development interface 902 without departing from the scope of one or more embodiments. For example, a Toolbox panel that renders a set of global editing tools—or links to a specific subset of editing tools of selected categories—may also be supported as a global panel.

In some embodiments, a panel's transition between visible and invisible states can be animated, such that invoking a panel causes the panel to slide from a designated edge of the development interface 902 (left, right or bottom), toward the middle of the interface 902 until the panel is fully extended and visible. Similarly, instructing a visible panel to switch to the hidden state causes the panel to retract toward the edge from which the panel initially extended.

Panels supported by the IDE system 202 can be generally classified into two types—global panels and content panels. Global panels are globally applicable to all development contexts, and can include, but are not limited to, the global panels discussed above. The visibility icons corresponding to global panels are always fixed on the panel control bar 920.

In contrast to global panels, content panels are not globally applicable, but rather are relevant or applicable only to a specific development task or context (e.g., ladder logic control programming, function block diagram control programming, sequential function chart control programming, structured text control programming, HMI screen development, device configuration, controller tag definition, etc.). Content panels can include, but are not limited to, a Layers panel that facilitates browsing through layers of graphical content (e.g., engineering drawings, HMI screens, etc.), an Alarms panel that renders configurable alarm definition data for selected alarm tags, a Logic Editor panel that renders selectable program elements that can be added to a ladder logic program (e.g., output coils, contacts, function blocks, etc.), an HMI screen development panel that renders selectable graphical elements that can be added to an HMI screen, or other such content panels. Visibility icons for content panels are located on the canvas toolbar 938 (see, e.g., FIG. 9 ) along the top edge of the canvas 940, and the set of content panel visibility icons available on the toolbar 938 is a function of the type of content (e.g., control programming, HMI development screens, etc.) rendered in the canvas 940. Thus, content panels will only be available for selection if the user is currently focused on the development task or context to which the content panel is relevant (based on which canvas 940 currently has focus within the development interface 902, and the type of project content rendered by the canvas 940). Example types of project content that can be associated with a dedicated set of content panels (and associated visibility icons) can include, but are not limited to, a ladder logic routine, a function block diagram routine, a structured text routine, a sequential function chart routine, a tag database, an HMI screen or application, a faceplate, various types of device views (e.g., controllers, drives, I/O modules, etc.), an engineering drawing, or other such content types.

In general, any of the panels associated with the left global panel area 922, right global panel area 928, or bottom global panel area 924 can be selectively set to be a pinned panel or an overlay panel. FIG. 11 a is a view of the top right corner of development interface 902 depicting a Properties panel 936 pinned in the right global panel area 928. Visibility icon 1010 a—corresponding to the Properties panel 936—is highlighted to indicate that the Properties panel 936 is visible. Any of the panels can be selectively set to be pinned or unpinned (i.e. overlaid) by selecting a suitable control; e.g., a control selected from a drop-down panel setting menu that can be invoked by selecting the panel menu icon 1102 in the top right corner of the panel. In some embodiments, a panel can also be selectively rendered as a pinned panel or as an overlay panel by selecting an appropriate control from a right-click menu associated with the corresponding visibility icon in the global panel control bar 920. Setting a panel to be pinned simulates pinning the panel to the background while visible, while setting a panel to be an overlay (unpinned) causes the panel to be rendered as an overlay over any pinned panels, or other interface content (e.g., canvas content), that may already be invoked in that part of the display.

When a pinned panel is invoked, user interface component 204 reduces the width of the canvas area 930 (or reduces the canvas area's height in the case of pinned panels in the bottom global panel area 924) to accommodate the pinned panel. This also causes one or more canvases 940 within the canvas area 930 to be similarly reduced in size. This can be seen in FIG. 11 a , where the right edge 1112 of the canvas area 930 has shifted toward the middle of the interface 902 to accommodate the width of the pinned panel 936, such that the right edge 1112 of the canvas area 930 is abutted against the left edge of the panel 936. When an overlay panel is invoked, the size of the canvas area 930 is not adjusted, and instead the panel is rendered as an overlay over a portion of the canvas, obscuring a portion of the canvas content behind the panel.

FIG. 11 b is a view of the top right corner of the development interface 902 depicting selection of an Online panel 1104 as an overlaid panel in the right global panel area 928. As shown in this figure, selection of the Online panel visibility icon 1010 b while the pinned Properties panel 936 is visible causes the Online panel 1104—which is currently set to be an overlay panel—to be displayed over the Properties panel. A panel set to be an overlay can be rendered with a shadow effect 1106 to convey that the panel is an overlay rather than a pinned panel (which is not rendered with a shadow effect). The width of the overlaid panel (e.g., Online panel 1104 in FIG. 11 b ) can be resized by clicking on or otherwise selecting the outer edge of the panel and sliding the edge inward or outward. Reducing the width of the overlay panel causes portions of any pinned panels underneath the overlay panel to be revealed. Although pinned and overlay panel effects are illustrated in FIGS. 11 a and 11 b with reference to the right global panel area 928, these effects are also applicable to the left global panel area 922 and bottom global panel area 924.

FIG. 11 c is a view of the top right corner of development interface 902 depicting two pinned panels—Properties panel 936 and Cross Reference Panel 1108— that are visible simultaneously. In this example, the Properties panel visibility icon 1010 a and the Cross Reference panel visibility icon 1010 b have been toggled on. Since both of these panels are currently set to be pinned panels, both panels 936 and 1108 are visible, stacked vertically in the right global panel area. In an example embodiment, if only one pinned panel is selected to be visible in a given area, that panel can be sized vertically to encompass the entire height of the panel area (e.g., right global panel area 928). If a second pinned panel is invoked, the two panels will be sized vertically such that both panels will fit within the panel area in a vertically stacked arrangement. The horizontal sizes of the stacked pinned panels can be changed by clicking and dragging the horizontal interface 1110 between the two panels upward or downward (where an upward drag decreases the size of the upper panel and increases the size of the lower panel, while a downward drag performs the reverse resizing).

In some scenarios, an overlaid panel may be sized or oriented to allow a portion of a pinned panel behind the overlaid panel to remain visible. FIG. 11 d is a view of the top right corner of development interface 902 in which a Toolbox panel 1114 is rendered as an overlay above Properties panel 936. However, the top of Toolbox panel 1114 is below the top of Properties panel 936, allowing a portion of the Properties panel 936 to remain visible. FIG. 11 e depicts a scenario in which the Toolbox panel 1114 of FIG. 11 d is switched to be a pinned panel, thereby causing panels 936 and 1114 to be stacked vertically.

As noted above, a panel can be set to be pinned by selecting a control associated with the panel. In some embodiments, a panel can also be pinned to a global panel area using a drag-and-drop action. FIG. 12 is a view of the top right corner of development interface 902 depicting a panel drop area 1202 for the right global panel area 928 according to such embodiments. According to an example embodiment, if no panels associated with the right global panel area 928 are set to be pinned (that is, the three available panels for the right global panel area 928 are currently set to be overlays, such that invoking the panel causes the panel to be rendered in the right global panel area 928 as an overlay), selecting the header icon 1004 for the right global panel area 928 causes an empty panel drop area 1202 to be rendered in the right global panel area 928. Any of the three panels available for the right global panel area 928 can be set to be pinned panels by dragging the corresponding visibility icon 1010 for the panel to the panel drop area 1202, as indicated by the arrow in FIG. 12 . Pinned panels can also be unpinned (that is, set to be overlay panels) by dragging the panels from the drop area 1202 back to the global panel control bar 920. This drag-and-drop approach can be used to pin panels to any of the three global panel areas (left, right, and bottom).

In some embodiments, pinned visible panels can also be selectively collapsed or expanded. FIG. 13 a depicts two horizontally stacked pinned panels (a Properties panel 936 and an Allocation panel 1302) in a default non-collapsed state. In this state, the content windows of both panels are visible below the respective header bars 1304 and 1306. A panel can be collapsed by selecting the header bar 1304 or 1306 corresponding to that panel. FIG. 13 b depicts the Allocation panel 1302 in the collapsed state as a result of clicking on or otherwise selecting the header bar 1306 for that panel. When the lower panel—the Allocation panel 1302 in this case—is collapsed, the content window for that panel is rendered invisible and the header bar 1306 moves to the bottom of the panel area, while the content window for the upper panel (the Properties panel 936 in this case) is lengthened to fill the remaining panel area space, exposing more of that window's content. FIG. 13 c depicts the Properties panel 936 collapsed as a result of clicking on or otherwise selecting the header bar 1304 for that panel. When the upper panel is collapsed, the content window for that panel is rendered invisible, and the header bar 1306 for the lower panel moves upward to a location just below the header bar 1304 of the upper panel. The content window of the lower panel fills the remaining panel area space, revealing more of the content of that panel.

Returning briefly to FIG. 9 , the canvas area 930 is the primary work area for the IDE system's development interface 902, and is bounded by the left global panel area 922, the right global panel area 928, the bottom global panel area 924, and the menu bar 904. In general, the canvas area 930 contains the one or more workspace canvases 940 on which the user interface component 204 renders components of the system project, such as ladder logic or other types of control code, program routines, controller tag definitions, development views of visualization screens, device configurations, engineering drawings, or other project components. The canvas area 930 is also the space with which the user interacts with these components—leveraging editing tools and information provided by the global and content panels—to perform such development functions as developing controller code (e.g., ladder logic, function block diagrams, structured text, etc.), developing visualizations for the automation system (e.g., HMI screens, AR/VR presentations, mashups, etc.), configuring device parameter settings, defining controller tags, developing engineering drawings, or other such project development functions.

FIG. 14 is a closer view of an example canvas 940 within the canvas area 930. Each canvas 940 within the canvas area 930 can be associated with at tab 932, selection of which brings the corresponding canvas 940 into focus. Canvas 940 can also have an associated toolbar 938 comprising selectable icons and/or fields that allows the user to set properties for the associated canvas 940, such as zoom levels, view formats, grid line visibility, or other such properties. In the example depicted in FIG. 14 , the canvas's toolbar 938 is located below tab 932.

In some embodiments, the canvas's toolbar 938 can also contain visibility icons for any content panels associated with the type of content (e.g., ladder logic, function block diagram, structured text, HMI screens in development, device parameters, engineering drawings, etc.) currently being rendered in the canvas 940. Similar to the global panel visibility icons located on the global panel control bar 920, selection of a content panel visibility icon from a canvas's toolbar 938 toggles the visibility of the panel associated with the selected icon. In some embodiments, when a content panel is made visible, the content panel can be rendered at a predefined designated location either in one of the global panel areas or adjacent to one of the global panel areas. Content panels may also be moved to a selected location within the interface workspace in some embodiments. Similar to global panels, content panels can be selectively set to be either pinned or overlaid.

Although the illustrated example depicts panel visibility icons as being rendered in the canvas's toolbar 938, panel visibility icons can also be rendered elsewhere on the development interface 902 in some embodiments; e.g., on the main tool bar 906 below the menu bar 904. In such embodiments, the list of panel visibility icons rendered in this space at a given time will be a function of the type of project content that currently has focus (e.g., the content of the particular canvas 940 that currently has focus). In other embodiments, user interface component 204 may add available content panel visibility icons to the global panel control bar 920 in their own designated grouping, based on the type of project content or development task currently being performed.

Canvas area 930 can comprise one or more tabbed canvases 940, with each canvas 940 associated with a tab 932. User interface component 204 allows the user to establish as many tabbed canvases 940 within the canvas area 930 as desired, with each tab 932 rendering a different aspect of the automation system project. Multiple tabbed canvases 940 can be stacked in the canvas area 930 either horizontally or vertically. FIG. 15 is a view of development interface 902 in which two canvases 940 a and 940 b have been stacked horizontally. Stacking tabs in this manner—either horizontally or vertically—allows content of both canvases 940 a and 940 b to be rendered simultaneously.

Users may also select to render multiple canvases 940 as overlays on top of one another. FIGS. 16 a and 16 b are views of two overlaid canvases 940 a and 940 b. In this example scenario, the first canvas 940 a is rendering a ladder logic routine being developed for an industrial controller, and the second canvas 940 b is rendering a tag database for the controller. FIG. 16 a depicts a scenario in which tab 932 a is selected, causing the corresponding ladder logic canvas 940 a to be rendered in the canvas area 930. FIG. 16 b depicts a scenario in which tab 932 b is selected, causing the corresponding tag database canvas 940 b to be rendered in the canvas area 930.

In the aggregate, the basic layout of the development interface 902 together with the panel control and tab manipulation functionalities described above can offer the user a fluid development workspace that affords a great deal of control over the balance between usable workspace and editing function availability. Moreover, since the user interface component 204 dynamically filters the available editing tools according to the user's current development task or focus—by making only a subset of content panels that are relevant to the current task available for selection—the development interface 902 substantially declutters the development workspace by removing panels and editing functions that are not relevant the task at hand.

FIGS. 17 a-17 e are views of various example layouts of the IDE system's development interface 902, illustrating increasing degrees of IDE content density that can be supported by the interface 902. FIG. 17 a is a view of interface 902 in which a single canvas 940 a is open and no left, right, or bottom panels are invoked. This substantially maximizes the size of the canvas 940 since no development workspace is being consumed by global or content panels, thereby displaying a substantially maximized amount of canvas content (e.g., control programming, tag database information, etc.). The panel control bar 920 remains pinned to the right-side edge of the development interface 902 to allow the user to invoke panels as needed. As noted above, in addition to the global panel visibility icons, the panel control bar 920 will render a relevant subset of visibility icons corresponding to content panels that are relevant to the task being performed in the active canvas 940 a (e.g., ladder logic programming, FBD programming, structured text programming, HMI screen development, device configuration, network configuration, etc.).

FIG. 17 b is a view of interface 902 in which an Explorer panel 910 has been rendered visible in the left global panel area 922 and a Properties panel 936 has been rendered in the right global panel area 928. These panels can be rendered visible using any of the techniques described above (e.g., selection from the panel control bar 920 or from the View menu option). Both panels 910 and 936 are set to be pinned, and so the canvas 940 a has been reduced in width to accommodate the panels 910 and 922 so that none of the canvas content 940 a is obscured by the panels.

FIG. 17 c is a view of development interface 902 in which a Layers panel 1702 (a content panel specific to the particular task being performed in the canvas 940 a) has been added to the previous view. The Layers panel 1702 has been added as an overlay panel to the left of the Properties panel 936, and so will obscure a portion of the canvas content corresponding to that space. FIG. 17 d adds further content to the previous view by adding a second canvas 940 b, which is stacked horizontally with the original canvas 940 a. The user can select which canvas 940 has the current focus by selecting the tab 932 a or 932 b corresponding to the desired canvas 940. This configuration allows the user to view content of both canvases 940 simultaneously (e.g., a control program and a tag database, a control program and a device view, etc.) while also affording the user access to the editing tools, information, and navigation structures associated with the Explorer panel 910, Properties panel 936, and Layers panel 1702.

FIG. 17 e is a view of development interface in which a third canvas 940 c is added to the previous view, stacked vertically with the two previous canvases 940 a and 940 b. As illustrated in this figure, canvases 940 can be selectively stacked either horizontally or vertically, or both horizontally and vertically, within the canvas area 930.

As illustrated by the examples depicted in FIGS. 17 a-17 e , the development interface's layout and customization features grant the user considerable flexibility with regard to customizing or curating canvas layouts and behaviors, as well as selective rendering of project data and editing tools. Moreover, editing tools and views available to the user at a given time are intelligently curated by the user interface component 204 as a function of the user's current development task or context, which may be determined based on the identity of the canvas 940 that currently has focus and the content of that canvas 940. For example, if the user selects a canvas 940 in which a structured text program is being developed, only a subset of the interface's total library of content panels that are relevant to structured text program development will be made available to the user (e.g., by adding visibility icons corresponding to those panels to the panel control bar 920).

Some of the global and content panels supported by some embodiments of the development interface will now be discussed. FIG. 18 is a view of the Explorer panel 910, which resides in the left global panel 922 area when invoked. Explorer panel 910 serves as a means for navigating and viewing content of a system project, and supports numerous ways for performing this navigation. The Explorer panel 910 itself supports a number of different viewing categories, which are represented by selectable explorer icons 1806 rendered on an explorer view control bar 908 pinned to the left-side edge of the Explorer panel 910. Selection of an explorer icon 1806 determines one or both of the type of project content to be browsed via the Explorer panel 910 or a format in which the browsable project content is rendered on the Explorer panel 910.

Explorer panel 910 also comprises a panel header 1802, the text of which identifies the set of explorer tools that are currently visible (e.g., “System” in FIG. 18 ). For explorer views that offer a choice of alternative presentation formats of the content represented by the explorer icon 1806, horizontally stacked tabs 1804 a and 1804 b are located below the panel header 1802 for selecting from among the available views. Below the tabs 1802 a and 1804 b (or below the header 1802 if the current Explorer tool set has only one view) is the Explorer panel content area 1808 in which the currently selected explorer tools are rendered. As will be discussed and illustrated below, the content rendered in the content area 1808 is a function of the explorer icon 1806 currently selected as well as the tab 1804 that currently has focus. For example, the selected explorer icon 1806 can determine the browsable project content to be rendered in the Explorer panel 910, and the selected tab 1804 determines a presentation format or organization of this browsable project content. For some views supported by Explorer panel 910, selection of an explorer icon 1806 may set a category of content to be rendered in the content area 1808, while selection of a tab can set the particular sub-category of rendered content within the main category.

FIGS. 19 a-19 b are views of the Explorer panel 910 in isolation, with the System view currently selected. The Explorer panel's System view can be invoked by selecting the System icon 1904 in the explorer view control bar 908. The System view offers two tabbed views—Logical (tab 1804 a) and Execution (tab 1804 b). FIG. 19 a depicts the Logical System view rendered in response to selection of the Logical tab 1804 a. The Logical System view renders a Logical System navigation tree 1902 in the content area 1808 comprising selectable nodes organized hierarchically. Selection of one of the nodes of the navigation tree 1902 associated with viewable project content causes content corresponding to the selected node to be rendered in the canvas 940 that currently has focus, or causes an appropriate panel to be rendered on the development interface 902 for display of the content (depending on the node selected and the corresponding content).

Project aspects that can be selected via the Logical System navigation tree 1902 can include, but are not limited to, control programs or routines (e.g., the RLL_01 and ST_01 nodes, which are listed in FIG. 19 a under the Prog1 and Prog2 parent nodes, respectively, in FIG. 19 ), tags and/or parameters associated with a program (e.g., Tags/Params nodes in FIG. 19 a , which are also listed under the parent nodes of their corresponding control programs), visualizations, alarm configurations, device configurations or parameter settings, trends, security settings, test results, or other such project aspects. In general, the nodes rendered in the Logical System navigation tree 1902 reflect elements that exist for the present automation system project.

In general, the Logical System view organizes system elements according to processes, production areas, or plant facilities within an industrial enterprise. FIG. 20 is an example Explorer panel 910 depicting a Logical System navigation tree 1902 for an example automation system project. As shown in this example, the Logical System navigation tree 1902 can organize aspects of the project hierarchically. The user can define parent nodes 2002 representing different processes, production areas, or plant facilities within the industrial enterprise (e.g., Extraction, Fermentation, Distillation, etc.). Sub-nodes 2004 can also be defined as child nodes of the parent nodes 2002 if the process, production area, or plant facility is to be further broken down into sections (e.g., LIC551, P561, PIC535, etc.).

Below one or more of these user-defined nodes are selectable nodes representing aspects of the parent node that can be viewed and configured by the user. These can include logic nodes 2006 representing control programming associated with the parent node, visualization nodes 2008 representing HMI applications or other types of visualization applications associated with the parent node, tags and parameter nodes 2010 representing tags and device parameters defined or configured for the parent node, device nodes (not shown in FIG. 20 ) representing devices associated with the parent node (e.g., industrial controllers, motor drives, etc.) or other such system project components. In general, the path through tree 1902 to a node represents a logical path to the corresponding project aspect, defined in terms of the user's plant layout or process layout.

FIG. 19 b is a view of the Explorer panel 910, in which the Execution System view rendered in response to selection of the Execution tab 1804 b. This view renders similar content to that of the Logical System view described above in connection with FIGS. 19 a and 20, but organized in a hierarchical Execution System navigation tree 1906 according to the execution devices (e.g., industrial controllers) on which the various aspects of the automation system reside and execute. This differs from the plant-based organization offered by Logical system navigation tree 1902. The path through tree 1906 to a node represents an execution path to the corresponding project aspect.

In some embodiments, the manner in which a user interacts with a node of the System navigation tree will determine how the content associated with the selected node is presented. FIG. 21 a illustrates an example response of the user interface component 204 when a user selects, but does not launch, a ladder logic node 2102 representing a ladder logic program of the system project (RLL_01). The node 2102 can be selected, for example, by performing a single mouse click on the node 2102 such that the node is highlighted. When the node 2102 is selected in this manner, information about the selected ladder logic program will be rendered in the Properties panel 936 (if the Properties panel 936 is currently visible).

FIG. 21 b illustrates an example response of the user interface component 204 when a user launches the ladder logic node 2102; e.g., by double-clicking on the node 2102. When a node in the System navigation tree 1902 or 1906 is double-clicked or otherwise instructed to launch, content or workspace associated with the node 2102 is rendered on a tabbed canvas 940. Double-clicking on the node 2102 can cause a new canvas 940 to be opened in the canvas area 930, or may cause a canvas 940 that currently has focus to render the content associated with the node 2102.

FIG. 21 c illustrates an example response of the user interface component 204 when a user right-clicks on the node 2102. Right-clicking on a node of the System navigation tree 1902 can cause a context menu 2104 to be rendered near the node 2102. Context menu 2104 renders a list of selectable options that are specific to the type of node selected. For example, if the selected node represents an industrial controller, context menu 2104 may list options to add an I/O module to the controller, to add a device to the controller (e.g., a drive), or options for other controller-specific configuration actions. The context menu 2104 may also include options for configuring the System navigation tree 1902 itself, such as copying, pasting, and deleting nodes.

FIGS. 22 a and 22 b are views of the Explorer panel 910 with the Application view currently selected. The Application view is invoked by selecting the Application icon 2202 in the explorer view control bar 908. The Application view lists applications (e.g., controller programs, HMI applications) that make up the automation system project in a browsable format. In this example, the Application view allows users to view controller application information by selecting the Controller tab 1804 a, and to view HMI application information by selecting an HMI tab 1804 b.

Selecting the Controller tab 1804 a renders a Controller navigation tree 2204 in the Explorer panel content area 1808. The Controller navigation tree 2204 comprises nodes representing controller tags, controller parameters, control programming (e.g., ladder logic, structured text, function block diagram, etc.), handler routines (e.g., fault handlers, power-up handlers, etc.), and other such aspects of industrial controllers that make up the automation system project. These nodes are organized in the Controller navigation tree 2204 according to the controller with which the nodes are associated. Selection of a controller application node can render property information for the selected controller application in the Properties panel 936 (e.g. via single-click interaction) or can render the code for the selected application in a canvas 940 (e.g., via double-click interaction). FIG. 23 is a view of a canvas 940 on which a portion of an example structure text program is rendered in response to selection of a structured text application node from the Controller navigation tree 2204 or the System navigation tree 1902. FIG. 24 is a view of a canvas 940 on which a portion of an example function block diagram program is rendered in response to selection of a function block diagram application node from the Controller navigation tree 2204 or the System navigation tree 1902.

Similarly, selecting the HMI tab 1804 b renders an HMI navigation tree 2206 in the Explorer panel content area 1808. This tree 2206 lists any HMI projects (or other types of visualization projects) associated with the automation system project, organized according to HMI server. Selection of an HMI application node can cause properties for the selected application to be rendered in the Properties panel 936, or can render the HMI application in a canvas 940.

FIG. 25 is a view of the Explorer panel 910 with the Devices view currently selected. The Device view is invoked by selecting the Devices icon 2502 in the explorer view control bar 908. The Devices view renders a Device navigation tree 2504 in the Explorer panel content area 1808. This tree 2504 comprises nodes representing devices (e.g., controllers, drives, motor control centers, etc.) that make up the control system project. Similar to the other Explorer views, information for a selected device can be rendered in the Properties panel 936 or on a canvas 940 by appropriate interaction with the device's node. FIG. 26 is a view of a canvas 940 on which information for an example controller is rendered in response to selection of a controller node from the Device navigation tree 2504. As shown in this example, information that can be rendered for a selected device can include, but is not limited to, a name and model of the device, a network address of the device, an overview description of the device, a firmware version currently installed on the device, a type of electronic keying, a connection type, or other such device information.

FIG. 27 is a view of the Explorer panel 910 with the Library view currently selected. The Library view is invoked by selecting the Library icon 2702 in the explorer view control bar 908. The Library view renders a Library navigation tree 2704 in the Explorer panel content area 1808. Library navigation tree 2704 comprises nodes representing software objects such as automation objects, add-on instructions, user-defined data types, device configurations, or other such objects. The Library view can include two or more tabs 1804 that allow the user to select sources of software objects to be viewed. In the illustrated example, tab 1804 a renders objects associated with the current automation system project, tab 1804 b renders objects available in a vendor library, and tab 1804 c renders objects from an external source. Similar to the other Explorer views, information regarding a selected object can be rendered in the Properties panel 936 or on a canvas 940 by appropriate interaction with the object's node.

FIG. 28 is a view of the Explorer panel 910 with the Extensions view currently selected. The Extensions view is invoked by selecting the Extensions icon 2802 in the explorer view control bar 908. The Extensions view renders a list of software extensions currently installed on the IDE system 202, which may include, but are not limited to, dashboards, system viewers and designers, ladder logic editors, function block diagram editors, structured text editors, HMI screen editors, or other such extensions.

Some embodiments of IDE system's user interface component 204 can also support multi-instance states of the project development environment, such that the development environment can be distributed across multiple display devices. Such embodiments can support multi-instance workflows that help to orient the user within the development environment and that allow the user to easily locate relevant editors within the expanded and distributed workspace, and to work fluidly across the multiple instances of the development interface 902.

FIGS. 29 a and 29 b depict an example distributed, multi-instance implementation of development interface 902. In this example, the development environment for an automation project currently being developed has been distributed across two monitors or other display devices, effectively expanding the development interface 902 across two separate but linked instances—development interface 902 a (FIG. 29 a ) rendered on a left-side monitor and development interface 902 b (FIG. 29 b ) rendered on a right-side monitor. In the illustrated example, the left-side interface 902 a renders a first canvas 940 a (and associated tab 932 a) on which is displayed a control routine currently being developed. Interface 902 a also renders the Explorer panel 910 and its associated explorer view control bar 908 in the left global panel area 922, a first instance of the Properties panel 936 a in the right global panel area 928, and a first instance of an overlaid Layers panel 2902 a adjacent to the Properties panel 936 a. A first instance of the panel control bar 920 a is anchored on the right edge of the interface 902 a.

The right-side interface 902 b renders two horizontally stacked canvases 940 b and 940 c (and their associated tabs 932 a and 932 b) containing two other aspects of the system project—a tag database and a parameter view, respectively. Second instances of the Properties panel 936 b and Layers panel 2902 b are rendered on the right-side of the interface 902 b, and a second instance of the panel control bar 920 b is anchored on the right edge of the interface 902 b. In this example scenario, the user has opted to omit the Explorer panel 910 from the right global panel area of the second interface 902 b.

Although only two instances of interface 902 are depicted in the example illustrated in FIGS. 29 a-29 b , the user interface component 204 can support expansion of the development interface 902 across any number of instances (e.g., if more than two display devices are available). Moreover, although the illustrated example depicts three opened canvases 940 a-940 c distributed across the two instances, any number of tabbed canvases 940 can be rendered on each instance of the interface 902.

The two interfaces 902 a and 902 b are extensions of one another, such that moving the cursor beyond the right boundary of left-side interface 902 a causes the cursor to enter the right-side interface 902 b via the left boundary of the right-side interface 902 b, and vice versa. Thus, the user can fluidly traverse across the three canvases 940 a-940 c. In general, the user can configure panel visibility and layouts independently for each extended interface 902 a and 902 b. For example, the user may opt to render copies of the same global panel on both interface instances, or may choose to render a given panel visible on one interface while omitting the panel from the other interface.

To assist the user to easily navigate between the interface instances, particularly in scenarios in which several tabbed canvases 940 are open, some embodiments of interface 902 can render an Available Tabs menu in response to selection of a suitable control (e.g., a control in the menu bar 904), which lists the tabs 932 that are currently open and available for selective focus. FIG. 30 is an example Available Tabs menu 3002 that can be invoked in such embodiments. Example menu 3002 lists the currently active canvases 940 according to name (e.g., Ladder 1, Tags, Parameters, etc.) and segregates the list according to the instance of interface 902 on which the respective canvases n940 currently reside. The list can be segregated vertically such that a first section 3004 lists the tabs 932 visible on the first instance of interface 902 and a second section 3006 lists the tabs 932 visible on the second instance. Selecting any of the tabs on the menu 3002 will cause the interface 902 to move the focus to the selected tab 936 (that is, bring the selected tab to the front of the workspace). By listing all active tabs in one menu 3002, a user can easily select a desired tab that may be located on an interface instance other than the one currently being viewed by the user, or that may be hidden under other overlaid canvases 940 or panels. This can mitigate the need to search through the distributed instances of interface 902 to locate a desired canvas 940.

Menu 3002 can also include other controls for manipulating the tabs 932. For example, a Consolidate menu option 3008 can cause all tab instances across the multiple interface instances to be moved to the interface instance currently being viewed (that is, the instance from which the Consolidate command was triggered). In some embodiments, performing this Consolidate function will also cause all extended instances of interface 902 to be closed, leaving only the currently viewed instance active.

A tab 932 and its associated canvas 940 can be moved from one instance of interface 902 to another by selecting and dragging the tab from its current instance of interface 902 to the target instance (e.g., a target instance on another display device). If a tab 932 is moved to an instance of interface 902 that already contains one or more visible canvases 940, the existing canvases will be resized to accommodate the addition of the canvas 940 associated with the relocated tab 932. In such cases, the canvases 940 can automatically determine a suitable configuration of horizontal and/or vertical stacking of the canvases 940 based on the current orientations of the preexisting tabs and the drop location of the relocated tab.

In some embodiments, layout and functionality of the development interface 902 can also be responsive to the size of the screen or display device on which the interface is rendered. The dimensions of the boundaries within which the interface 902 operates can be a function of the dimensions of the device's display screen, or may be set by the user by resizing the IDE system's development environment window. In either case, user interface component 204 can be configured to enable or disable certain functions of the development interface 902 based on the size or aspect ratio of the interface's boundaries, and to reorganize elements of the development interface 902 as needed to fill the available horizontal and vertical viewport space as a function of available space.

In an example embodiment, development interface 902 can support multiple layout modes corresponding to respective ranges of screen or window widths. FIGS. 31 a-31 d are example instances of development interface 902 that accord to respective different layout modes as a function of available screen width.

FIG. 31 a depicts a first layout mode suitable for scenarios in which there are no width restrictions. This first layout mode offers full support for all primary interface elements, as described above.

FIG. 31 b depicts a second layout mode that may be initiated by user interface component 204 when the available screen width is below a first threshold width. According to this second layout mode, global panel sections (e.g., Properties panel 936) are removed, and pinned panels are prohibited (that is, all panels are rendered as overlay panels). Left and bottom panel support is disabled, and only global right overlay panels are permitted to be rendered. Only one panel is permitted to be rendered at a given time. Content panel visibility icons, which are normally rendered on the canvas's tool bar, are moved to the global panel control bar 920 (e.g., Layers visibility icon 3102). Support for multiple stacked canvases is disabled. The Explorer panel 910, including its associated explorer view control bar 908, is moved from the left side to the right side of the interface 902 adjacent to the global panel control bar 920.

FIG. 31 c depicts a third layout mode that may be initiated by user interface component 204 when the available screen width is below a second threshold width that is smaller than the first threshold width. This third layout mode maintains all limitations and restrictions of the second layout mode. In addition, header elements are collapsed to reduce the number of selections visible at the same time. This includes collapsing the visible selection on menu bar 904 into a single selectable menu icon 3104, which can be selected to render the menu bar options as a drop-down list. Similarly, the selections on the tool bar 906 are collapsed into a single Tools icon 3108, which can be selected to render the tool bar selections in another drop-down list. Search bar 934 is also reduced to a selectable Search icon 3110. As a result of these consolidations, the total number of visible selections is reduced, thereby decluttering the limited development space.

As discussed above in connection with FIGS. 7 and 8 , system projects 302 that have been developed using the IDE system 202 can be deployed to one or more target control devices for execution. In the case of industrial control code—e.g., control program files 702—this involves downloading the compiled control program to an industrial controller 118, which then executes the program in connection with monitoring and controlling its associated industrial assets. After the control program has been deployed to the controller 118, one or more control developers may subsequently submit edits to either the online version of the program or an offline copy of the program stored locally on the developer's client device or as an offline version stored on the IDE system 202. This can yield differences between the online and offline versions of the control program. In a collaborative development environment in which multiple developers are permitted to access and edit the control program, this can also give rise to several versions of the control program, including the online version currently executing on the industrial controller 118 as well as any offline versions of the program that may differ from the online version due to edits that have been submitted by the developers to their local copies of the program but have not been downloaded to the controller 118. Differences between offline and online versions of the control program can also result from edits submitted by a first developer directly to the online program which have not yet been synchronized to the local offline version belonging to a second developer. To assist in coordinating these collaborative edits, some embodiments of IDE system 202 can include tools that manage differencing between these various versions of a control program, that graphically convey the various online and offline states of a control program, and that render notifications informing the program developers of pending edits submitted by other developers.

FIG. 32 is a diagram illustrating an embodiment of IDE system 202 that resides on a cloud platform 806 and executes as a set of cloud-based IDE service 802 that are accessible to authorized remote client devices 504. This architecture allows multiple users to access and utilize the industrial IDE services 802 for development of industrial control programs to be downloaded to and executed on industrial controllers 118 at plant facilities.

The illustrated example assumes that an online version of a control program (online program 3202) has already been deployed to industrial controller 118 and is currently being executed to facilitate monitoring and control of a corresponding automation system. Subsequently, multiple different remote client devices 504 can leverage the centralized industrial IDE services 802 to individually submit further design input 512 directed to the control program using development interface 902. These edits 512 may be offline edits directed to an offline version of the program stored on the respective client devices 504 (offline programs 3204) or online edits that are submitted directly to the online program 3202. Using this architecture, multiple remote developers can submit design input 512 to a common industrial automation system project 302, facilitating parallel development by multiple remote designers. The industrial IDE system 202 can support collaborative design tools that manage and regulate these diverse sets of design input 512 to ensure consistency and optimization of the control program.

In the example depicted in FIG. 32 , the development interfaces described above are delivered to the client devices 504 in a secure manner, and developers at each client device 504 can submit design input 512 directed to the online program 3202 or an offline version of the program 3204 stored locally on the client device 504 or on the cloud platform 806 (FIG. 32 illustrates a scenario in which each user's offline version of the program 3204 is stored on the cloud platform 806). As discussed above, IDE services 802 will generate and render individual design feedback 518 to each user's client device 504 as each user proceeds through their program editing workflow. that may assist in developing their industrial control projects.

FIG. 33 depicts an implementation of development interface 902 that includes visual tools for informing developers of differences that exist between the online version of a control program 3202 and their local offline version of the control program 3204. Similar to the versions of the development interface 902 discussed above, this version comprises a workspace canvas 940 whose contents are determined based which of the tabs 932 are currently selected. Development interface 902 also includes a global panel control bar 920 on the right-side edge of the interface 902, a menu bar 904 along the top edge of the interface 902, and a tool bar 906 below the menu bar 904.

Explorer panel 910 resides on the left side of the interface 902, with an explorer view control bar 908 pinned to the left-side edge of the Explorer panel 910. The explorer panel 910 is currently displaying the system navigation tree 1902, which comprises selectable nodes organized hierarchically. Selection of one of the nodes of the navigation tree 1902 causes content corresponding to the selected node to be rendered in the canvas 940 that currently has focus, or causes an appropriate panel to be rendered on the development interface 902 for display of the content (depending on the node selected and the corresponding content).

FIGS. 34 a-34 c are views of the Explorer panel 910 in isolation, with the System view currently selected. As depicted in these views, nodes of the navigation tree 1902 can be selectively expanded or collapsed so that child nodes below a parent node can be selectively displayed or hidden. FIG. 34 a depicts a view in which the navigation tree 1902 is completely collapsed into a single project node (AO1). Selection of this parent node causes nodes representing the control programs associated with the project—Prog1, Prog2, and Prog3—to be displayed in the navigation tree 1902, as depicted in FIG. 34 b . Selection of any of these program nodes reveals, below the selected node, nodes representing the control routines that make up the selected program (e.g., RLL_01, RLL_02, etc.), a node for invoking the tag database and configuration parameters for the program (e.g., Tags/Parameters), and any other nodes representing aspects of the selected program (e.g., visualizations, alarm configurations, trends, security settings, test results, or other such project aspects).

Explorer panel 910 can also render color-coded indicator bars 3206 beside respective nodes of the navigation tree 1902. In the illustrated examples, indicator bars 3206 comprise vertical indicators to the left of each node. The color of the indicator bar 3206 beside a node of the navigation tree 1902 indicates whether a version of the program represented by the node is currently installed on an industrial controller 118 to which the user is connected via the IDE system 102, or alternatively whether the program exists solely as an offline program that has not yet been downloaded to the controller 118.

For example, as shown in FIG. 34 a , indicator bar 3206 a next to the project node AO1 is a color—e.g., green—indicating that at least one of the programs associated with that project is installed and running on the industrial controller 118 as an online program 3202 (note that the green indicator bars 3206 are depicted as black in the figures). Expanding the project node to display the program nodes, as shown in FIG. 34 b , reveals that two programs—Prog1 and Prog3—have green indicator bars 3206 b and 3206 d. The indicator bar 3206 c associated with another program—Prog2—is a different color—e.g., grey—indicating that this program exists only as an offline program 3204 and has not yet been downloaded to an industrial controller 118. This offline program 3204 may be, for example, a program being written offline for subsequent download to a controller, and which currently only exists as an offline program 3204 that is stored either locally on the user's client device 504 or on the cloud platform 806 in association with the system project.

Expanding the program nodes, as shown in FIG. 34 c , reveals that the indicator bars 3206 e next to the routines of Prog1 are green, indicating that these routines are currently active in the controller 118. By contrast, the indicator bars 3206 f next to the routine nodes of Prog2 are grey, indicating that these routines only exist as offline routines and have not been sent to a controller 118.

In the present example, it is assumed that the routines of Prog3 are currently installed and executing on an industrial controller 118, but that a developer has submitted an offline edit to the routine named RLL_01 of that program. Consequently, this results in a difference between the version of routine RLL_01 stored in the offline version of the program 3204 and the version of RLL_01 in the online version of the program 3202. To convey this online and offline difference, the node representing RLL_01 is marked with a dot 3306 or other symbol. This dot 3306 indicates that routine RLL_01 exists in both the online program 3202 and its corresponding offline version (offline program 3204) but that the offline and online versions do not match due to submission of an offline edit that has not yet been downloaded to the controller 118. The indicator bar 3206 next to the node corresponding to this mismatched routine can also be distinguished with a third color or a pattern to further indicate this difference between the online and offline state.

The dot 3306 can also be used to indicate when a difference exists between the offline routine and its corresponding online routine due to an edit that was submitted to the online version of the routine but which has not yet been synchronized to the user's offline version of the routine. In some embodiments, the color of the dot 3306 can be set to convey whether an edit exists on the online program 3202 that is available to be synchronized to the offline version of the program 3204, or alternatively whether an edit exists on the offline program 3204 that is available to be synchronized to the online program 3202.

Navigation tree 1902 can use similar labeling to indicate when a routine exists in an industrial controller 118 to which the user is connected but does not exist in the user's offline copy of the project. For example, if a new routine is added to the controller 118 by a first developer, the navigation tree 1902 can render a node on a second developer's development interface 902 representing this new routine. The user interface component 204 can label this node with an indicator bar 3206 having a color that identifies the routine as one that exists in the controller 118 but which has no corresponding offline version in the second developer's local version of the program 3204.

Using this marking standard, the navigation tree 1902 can clearly convey to developers the online and offline differencing statuses of the programs and routines that make up a project. As will be described in more detail below, the IDE system 202 can resolve differences between online and offline versions of a program.

Returning to FIG. 33 , the user interface component 204 can also render color-coded tab indicators 3302 on the tabs 932 associated with respective workspace canvases 940. In the example illustrated in FIG. 33 , these tab indicators 3302 comprises vertical boxes located at the left-side edge of each tab 932. The colors of these tab indicators 3302 can convey similar information to that conveyed by the vertical bars in the navigation tree 1902. For example, tabs 932 corresponding to routines that only exist offline but have not yet been deployed to a controller 118 can be assigned tab indicators 3302 having a first color (as in the case of tab indicator 3302 c), while tabs 932 corresponding to routines that have been deployed to a controller 118 and which match their corresponding offline versions can be assigned tab indicators 3302 having a second color (as in the case of tab indicator 3302 b).

When a developer submits an edit to an offline version of a control routine whose online version is running on a controller 118, the navigation tree will indicate the mismatch between the online and offline versions with a dot 3306 next to the node corresponding to the mismatched routine, as discussed above. The user interface component 204 also changes the color of the tab indicator 3302 corresponding to that routine to a color indicating that the offline version of the routine does not match its corresponding online version on the controller 118 (as in the case of tab indicator 3302 a). The dot 3306 is also rendered on a developer's navigation tree 1902 when another developer submits an edit to the online version of the program 3202 that has not yet been synchronized to the first developer's offline version of the program 3204, and this state can also be indicated by the color of the tab indicator 3302 corresponding to the mismatched routine.

If a mismatch exists between an online version of a program 3202 and its corresponding offline version 3204 due to offline edits submitted by a user (as indicated by a dot 3306 next to the edited routine), the user can synchronize the pending edits to the online version of the program 3202 by selecting a synchronize button 3304 in the tool bar 906. In some embodiments, the development interface 902 can render an indication near this synchronize button 3304, or otherwise change the visual state of this button 3304, when pending offline edits are available to be synchronized to the controller 118.

The synchronize button 3304 can also trigger a synchronization of updates from the online program 3202 to an offline version of the program 3204. For example, if a user remotely interfaces with the online program 3202 that is currently executing on the controller 118, and the collaboration management component 210 determines that the online program 3202 has been modified relative to the user's offline version of the program 3204, the user interface component 204 can render various notifications on the user's development interface 902 to convey that the online program 3202 includes edits that have not been synchronized to the user's local version of the program 3204. To notify the user of these changes, the user interface component 204 can change the color of the vertical indicator 3206 and/or tab indicator 3302 corresponding to any routines that have been modified on the controller 118. The user interface component 204 can also indicate, within the workspace canvas 940, the portions of the program that have been modified (e.g., by highlighting the ladder logic rungs that have been changed, added, or deleted; by highlighting instruction parameters that have been modified, etc.). In some embodiments, the development interface 902 can also display information about the edits, including an identity of the developer who submitted the edits to the online program 3202 and any development notes submitted by the originator of the edits explaining a reason for the changes. The user can then choose to synchronize these changes to his or her personal offline version of the program 3404 by selecting the synchronize button 3304.

To coordinate edits made to both online and offline versions of a control program within a collaborative development environment in which multiple developers view and edit a common control project, IDE system 202 can include a collaboration management component 210 that tracks these collaborative edits, notifies developers of edits submitted by other users, intelligently resolves differences between the various online and offline versions of the system project, and creates a change history for each system project. In an example scenario, a first and second developer may be viewing, on their respective development interfaces 902 rendered on client devices 504 a and 504 b, an active program 3202 that is currently running on a controller 118. The first developer (at client device 504 a) may use development interface 902 to edit the online version of the program 3202 while the second developer is viewing (on client device 504 b) the portion of the program 3202 that has been edited by the first developer. As part of the commissioning process for the edit, the development interface 902 can prompt the first developer to enter a comment about the edit. When the edit is finalized and deployed to the controller 118, the collaboration management component 310 stores a record of the edit and the comment in an edit history for the project, which is maintained on cloud storage by the IDE system 202. The edit history comprises log entries for each edit submitted to the online program 3202, where each entry includes at least an indication of the part of the program that has been edited, the nature of the edit, the developer-submitted comment, and an identity of the developer who submitted the edit.

When the edit is submitted while the second developer is viewing the portion of the online program 3202 affected by the edit, the second developer's development interface 902 can automatically refresh the view of the program 3202 in the second user's workspace canvas 940 to reflect the edit, and can also render a notification that the edit has been made. The notification can indicate, within the workspace canvas 940, the portion of the program 3202 that has been affected by the edit. The notification may also identify the first developer who submitted the edit and display the first developer's comments about the edit. Alternatively, the notification may only provide a minimal notice that the program 3202 has been edited, and the second developer can then choose to review the edit history to learn about the edit if desired.

In some embodiments, if a difference exists between an online program 3202 and a user's offline version of the program 3204, as an alternative to allowing the user to choose whether to synchronize the local version to the controller 118 or to update the offline version to reflect the running version, the collaboration management component 210 can intelligently determine which version of the control program satisfies one or more suitability criteria and perform a synchronization operation based on this determination. In some scenarios, this may involve performing a partial synchronization of offline edits to the controller 118 such that only a selected subset of offline edits are deployed to the online program 3202 while the remaining edits are omitted from the synchronization process. The determination of whether a user's offline edits are to be synchronized to the controller 118, and which of the edits are to be send to the controller 118, can be based on any suitable optimization criteria, including but not limited to a determination of which version of the control program (e.g., which subset of the proposed edits) will perform a given task with the least amount of code, which version will result in the least energy consumption by the controlled industrial assets, which version will have the smallest impact on machine lifecycle, or other such criteria. In some embodiments, this intelligent synchronization can be triggered by selecting the synchronize button 3304.

In another scenario, a first developer may be editing an offline version of a program 3204 at the same time that a second developer is submitting online edits to the online version of the program 3202. As a result, the first developer's offline version of the program 3204 no longer matches the online program 3202 due to both the changes made to the first developer's offline program 3204 and the edits made to the online version by the second developer. As in previous examples, development interface displays a dot 3306 in the navigation tree 1902 beside any of the nodes corresponding to a routine of the program that differs between the offline and online versions, due to either an offline edit made by the first developer that is not in the online version or an edit in the online program 3202 made by the second developer that is not present in the offline program 3204.

In some embodiments, development interface 902 can convey these two types of program differences by rendering two different tabs 932 and corresponding workspace canvases 940 for the same routine—a first tab 932 for the online version of the program 3202 including the new edits that have been submitted by the second developer, and a second tab 932 for the offline version including the offline edits prepared by the first developer. This allows the first developer to review both sets of edits in adjacent tabs 932 to determine whether the second developer's online edits conflict with the first developer's proposed offline edits, or necessitate a change to the offline edits. The first developer can then choose to either merge the two sets of edits and update the offline version accordingly, or to abort the offline edits and only synchronize the second developer's online edits to the first user's offline version of the program 3204, thereby bringing the offline version up to date with the online changes.

Alternatively, rather than rendering the differing online and offline versions of the program in two separate tabs 932, some embodiments of the development interface 902 may render both the first developer's offline edits and the second developer's online edits within the same workspace canvas 940 with suitable differentiations. The first developer can then selectively synchronize some or all of the offline edits to the online program 3202 based on a determination of whether the offline edits are compatible with the second developer's online edits. The first developer may also choose to merge all online and offline edits with one action by selecting the synchronize button 3304, which causes all offline edits to be synchronized to the controller 118 and all online edits to be synchronized to the first developer's offline version of the program 3204, thereby resolving all differences between the online and offline versions.

In some embodiments, if the online and offline edits include modifications that are directed to the same section of the control program and are incompatible with one another, the collaboration management component 210 can apply selection criteria to determine which version of the edits should be applied to the running version of the program 3202. In such embodiments, this brokering process can be initiated by the first developer by selecting the synchronize button 3304. The collaboration management component 210 can apply any suitable criterion in connection with selecting the preferred version of the edits. For example, in some embodiments collaboration management component 210 can select the edit that is predicted to perform the same control function with the least lines of code. In another example, collaboration management component 210 may select the edit that is predicted to control its associated mechanical asset with the least stress on the machinery. In this case, estimations of the amount of stress applied to the controlled industrial assets can be determined by the collaboration management component 210 based on an analysis of the respective versions of the control code in view of built-in industrial expertise regarding how the respective control sequences will affect the mechanical assets.

For example, collaboration management component 210 may analyze each version of the control code—a version with the online edits applied and a version with the alternative offline edits applied—to determine an estimated machine cycle frequency that will result from execution of each version of the program. Since higher frequencies correlate to faster machine wear, collaboration management component 210 may select the version that is estimated to perform the control function with a smallest machine cycle frequency without causing the product throughput to fall below a defined minimum. In another example, collaboration management component 210 may estimate expected ranges of motion of a mechanical asset (e.g., a motion device) that will be implemented by each version of the program, or a number of individual mechanical motions that will be implemented by the respective versions of the program to perform the same function, and select the edits that are expected to implement the control function using the shortest motions or least number of motions. Other types of predictive control analysis and corresponding edit selection criteria are within the scope of one or more embodiments. Based on results of such analyses, collaboration management component 210 can select either the offline edits or the current online edits as being a most suitable version. If the offline edits are selected, these offline edits are synchronized to the online program 3202— overriding the online edits—and the second developer's development interface 902 renders a notification that the previously submitted online edits have been overwritten by the first developer. Alternatively, if the online edits are selected, these edits are synchronized to the user's offline version of the program 3204 and the pending offline edits are discarded.

According to another feature relevant to collaborative environments, some embodiments of the IDE system 202 can allow selective locking and unlocking of online editing while a user is performing online editing of the control program 3202 using development interface 902. For example, while a first developer is using the IDE system 202 to view and edit the online version of the program 3202, the first developer can elect to lock other developers out of online edit mode, preventing other developers from submitting online edits to the program 3202. While in this mode, the IDE system 202 permits other developers to view the online program 3202 but prevents submission of edits to the program 3202 from the development interfaces 902 of those other developers.

If desired, the first developer may elect to unlock online editing for a selected second developer, allowing the second developer to both view and edit the online program 3202 in parallel with the first developer. In some embodiments, when a developer unlocks online editing for another developer, the workspace canvases 940 presented to the respective developers act as a shared canvas for simultaneous editing of the online program 3202, such that edits submitted by the first developer are reflected in the second developer's workspace canvas 940 and vice versa. This can facilitate simultaneous collaborative editing of the online program 3202 by two or more developers.

The graphical indicators and notification features supported the development interface 902 can clearly convey the relative online and offline states of industrial control programs within the context of a collaborative development environment. These features allow users to quickly distinguish between control routines that exist solely as offline versions, routines that are executing on a controller but do not exist in the user's offline project, routines that exist in both the online and offline versions of a program but which differ due to submission of online or offline edits, and routines that match in both their online and offline versions. Collaborative management features supported by embodiments of the IDE system 202 notify users of edits submitted by other users and assist in coordinating submission of program edits and synchronization of program versions within the development platform.

FIGS. 35 a-35 c illustrate a methodology in accordance with one or more embodiments of the subject application. While, for purposes of simplicity of explanation, the methodology shown herein are shown and described as a series of acts, it is to be understood and appreciated that the subject innovation is not limited by the order of acts, as some acts may, in accordance therewith, occur in a different order and/or concurrently with other acts from that shown and described herein. For example, those skilled in the art will understand and appreciate that a methodology could alternatively be represented as a series of interrelated states or events, such as in a state diagram. Moreover, not all illustrated acts may be required to implement a methodology in accordance with the innovation. Furthermore, interaction diagram(s) may represent methodologies, or methods, in accordance with the subject disclosure when disparate entities enact disparate portions of the methodologies. Further yet, two or more of the disclosed example methods can be implemented in combination with each other, to accomplish one or more features or advantages described herein.

FIG. 35 a illustrates a first part of an example methodology 3500 a for rendering graphical indications of online and offline states of an industrial control program on an industrial IDE system. Initially, at 3502, an explorer panel is rendered on the development interface of an industrial IDE. The explorer panel is configured to facilitate browsing and selecting of aspects of an industrial automation project (e.g., control programming or routines, HMI development screens, controller tag databases, industrial device parameter configurations, alarm configurations, etc.) to be rendered on a workspace canvas of the development interface. The explorer panel can comprise a set of selectable icons representing respective viewing categories. The aspects of the project represented by the nodes include one or more control programs and their associated routines.

At 3504, an indicator is rendered beside a node in the explorer panel corresponding to a routine of a control program. Prior to remotely interfacing with a physical industrial controller, the indicator is initially displayed in a first color indicating that the routine exists in an offline version of the program currently being viewed on the development interface.

At 3506, a tabbed workspace canvas is rendered on the development interface. The tabbed workspace canvas displays the routines of the control programs, such that respective tabs of the tabbed workspace canvas correspond to the routines. In this arrangement, selection of a tab causes the workspace canvas to display the routine corresponding to the selected tab in the workspace canvas.

At 3508, a determination is made as to whether an instruction to go online with an industrial controller is received by the IDE system. The industrial controller may be executing an online version of the control program being viewed on the development interface, or may be executing another control program that is not currently part of the user's offline project file. If an instruction to go online with the industrial controller is received (YES at step 3508), the methodology proceeds to step 3510, where the IDE system remotely connects to the specified industrial controller and reads the online program installed on that controller.

The methodology then proceeds to the second part 3500 b illustrated in FIG. 35 b . At 3512, a determination is made as to whether the routine of the offline version of the control program corresponds to a routine of the online program currently installed on the controller. If the controller includes a routine that corresponds to the routine of the offline version of the program (YES at step 3512), the methodology proceeds to step 3514, where the color of the indicator beside the node corresponding to the routine is set to be a second color indicating that the routine exists in both the offline version of the program and the online version of the program that is installed and executing on the controller.

At 3516, a determination is made as to whether the online version of the routine matches the offline version of the routine. If both versions match (YES at step 3516), the methodology returns to step 3512. Alternatively, if the two versions of the routine do not match due to an edit submitted to either of the offline version or the online version of the routine (NO at step 3516), the methodology proceeds to step 3518, where a symbol (e.g., a dot or another type of symbol) is rendered beside the node corresponding to the routine. This symbol indicates that the online version of the routine does not match the offline version of the routine. In such a scenario, the development interface may indicate, in the workspace canvas, the differences between online and offline versions of the routine (e.g., a newly added or deleted rung of the ladder logic programming, a modified instruction parameter, etc.). The user may also choose to synchronize the two versions by either writing the offline version of the routine to the controller or synchronizing the edits made to the online version to the offline version.

If it is determined at step 3512 that the routine of the offline program does not have a corresponding routine in the online program (NO at step 3512), the methodology proceeds to the third part 3500 c illustrated in FIG. 35 c . At 3520, a node is added to the navigation tree representing a routine that exists in the online program that does not exist in the offline project currently being viewed on the development interface. In this scenario, the development interface can allow the user to synchronize a copy of the routine to the offline version of the project if desired.

In order to provide a context for the various aspects of the disclosed subject matter, FIGS. 36 and 37 as well as the following discussion are intended to provide a brief, general description of a suitable environment in which the various aspects of the disclosed subject matter may be implemented. While the embodiments have been described above in the general context of computer-executable instructions that can run on one or more computers, those skilled in the art will recognize that the embodiments can be also implemented in combination with other program modules and/or as a combination of hardware and software.

Generally, program modules include routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the inventive methods can be practiced with other computer system configurations, including single-processor or multiprocessor computer systems, minicomputers, mainframe computers, Internet of Things (IoT) devices, distributed computing systems, as well as personal computers, hand-held computing devices, microprocessor-based or programmable consumer electronics, and the like, each of which can be operatively coupled to one or more associated devices.

The illustrated embodiments herein can be also practiced in distributed computing environments where certain tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote memory storage devices.

Computing devices typically include a variety of media, which can include computer-readable storage media, machine-readable storage media, and/or communications media, which two terms are used herein differently from one another as follows. Computer-readable storage media or machine-readable storage media can be any available storage media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable storage media or machine-readable storage media can be implemented in connection with any method or technology for storage of information such as computer-readable or machine-readable instructions, program modules, structured data or unstructured data.

Computer-readable storage media can include, but are not limited to, random access memory (RAM), read only memory (ROM), electrically erasable programmable read only memory (EEPROM), flash memory or other memory technology, compact disk read only memory (CD-ROM), digital versatile disk (DVD), Blu-ray disc (BD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, solid state drives or other solid state storage devices, or other tangible and/or non-transitory media which can be used to store desired information. In this regard, the terms “tangible” or “non-transitory” herein as applied to storage, memory or computer-readable media, are to be understood to exclude only propagating transitory signals per se as modifiers and do not relinquish rights to all standard storage, memory or computer-readable media that are not only propagating transitory signals per se.

Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium.

Communications media typically embody computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and includes any information delivery or transport media. The term “modulated data signal” or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals. By way of example, and not limitation, communication media include wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media.

With reference again to FIG. 36 , the example environment 3600 for implementing various embodiments of the aspects described herein includes a computer 3602, the computer 3602 including a processing unit 3604, a system memory 3606 and a system bus 3608. The system bus 3608 couples system components including, but not limited to, the system memory 3606 to the processing unit 3604. The processing unit 3604 can be any of various commercially available processors. Dual microprocessors and other multi-processor architectures can also be employed as the processing unit 3604.

The system bus 3608 can be any of several types of bus structure that can further interconnect to a memory bus (with or without a memory controller), a peripheral bus, and a local bus using any of a variety of commercially available bus architectures. The system memory 3606 includes ROM 3610 and RAM 3612. A basic input/output system (BIOS) can be stored in a non-volatile memory such as ROM, erasable programmable read only memory (EPROM), EEPROM, which BIOS contains the basic routines that help to transfer information between elements within the computer 3602, such as during startup. The RAM 3612 can also include a high-speed RAM such as static RAM for caching data.

The computer 3602 further includes an internal hard disk drive (HDD) 3614 (e.g., EIDE, SATA), one or more external storage devices 3616 (e.g., a magnetic floppy disk drive (FDD) 3616, a memory stick or flash drive reader, a memory card reader, etc.) and an optical disk drive 3620 (e.g., which can read or write from a CD-ROM disc, a DVD, a BD, etc.). While the internal HDD 3614 is illustrated as located within the computer 3602, the internal HDD 3614 can also be configured for external use in a suitable chassis (not shown). Additionally, while not shown in environment 3600, a solid state drive (SSD) could be used in addition to, or in place of, an HDD 3614. The HDD 3614, external storage device(s) 3616 and optical disk drive 3620 can be connected to the system bus 3608 by an HDD interface 3624, an external storage interface 3626 and an optical drive interface 3628, respectively. The interface 3624 for external drive implementations can include at least one or both of Universal Serial Bus (USB) and Institute of Electrical and Electronics Engineers (IEEE) 1394 interface technologies. Other external drive connection technologies are within contemplation of the embodiments described herein.

The drives and their associated computer-readable storage media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer 3602, the drives and storage media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable storage media above refers to respective types of storage devices, it should be appreciated by those skilled in the art that other types of storage media which are readable by a computer, whether presently existing or developed in the future, could also be used in the example operating environment, and further, that any such storage media can contain computer-executable instructions for performing the methods described herein.

A number of program modules can be stored in the drives and RAM 3612, including an operating system 3630, one or more application programs 3632, other program modules 3634 and program data 3636. All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM 3612. The systems and methods described herein can be implemented utilizing various commercially available operating systems or combinations of operating systems.

Computer 3602 can optionally comprise emulation technologies. For example, a hypervisor (not shown) or other intermediary can emulate a hardware environment for operating system 3630, and the emulated hardware can optionally be different from the hardware illustrated in FIG. 36 . In such an embodiment, operating system 3630 can comprise one virtual machine (VM) of multiple VMs hosted at computer 3602. Furthermore, operating system 3630 can provide runtime environments, such as the Java runtime environment or the .NET framework, for application programs 3632. Runtime environments are consistent execution environments that allow application programs 3632 to run on any operating system that includes the runtime environment. Similarly, operating system 3630 can support containers, and application programs 3632 can be in the form of containers, which are lightweight, standalone, executable packages of software that include, e.g., code, runtime, system tools, system libraries and settings for an application.

Further, computer 3602 can be enable with a security module, such as a trusted processing module (TPM). For instance with a TPM, boot components hash next in time boot components, and wait for a match of results to secured values, before loading a next boot component. This process can take place at any layer in the code execution stack of computer 3602, e.g., applied at the application execution level or at the operating system (OS) kernel level, thereby enabling security at any level of code execution.

A user can enter commands and information into the computer 3602 through one or more wired/wireless input devices, e.g., a keyboard 3638, a touch screen 3640, and a pointing device, such as a mouse 3642. Other input devices (not shown) can include a microphone, an infrared (IR) remote control, a radio frequency (RF) remote control, or other remote control, a joystick, a virtual reality controller and/or virtual reality headset, a game pad, a stylus pen, an image input device, e.g., camera(s), a gesture sensor input device, a vision movement sensor input device, an emotion or facial detection device, a biometric input device, e.g., fingerprint or iris scanner, or the like. These and other input devices are often connected to the processing unit 3604 through an input device interface 3644 that can be coupled to the system bus 3608, but can be connected by other interfaces, such as a parallel port, an IEEE 1394 serial port, a game port, a USB port, an IR interface, a BLUETOOTH® interface, etc.

A monitor 3644 or other type of display device can be also connected to the system bus 3608 via an interface, such as a video adapter 3646. In addition to the monitor 3644, a computer typically includes other peripheral output devices (not shown), such as speakers, printers, etc.

The computer 3602 can operate in a networked environment using logical connections via wired and/or wireless communications to one or more remote computers, such as a remote computer(s) 3648. The remote computer(s) 3648 can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment appliance, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer 3602, although, for purposes of brevity, only a memory/storage device 3650 is illustrated. The logical connections depicted include wired/wireless connectivity to a local area network (LAN) 3652 and/or larger networks, e.g., a wide area network (WAN) 3654. Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which can connect to a global communications network, e.g., the Internet.

When used in a LAN networking environment, the computer 3602 can be connected to the local network 3652 through a wired and/or wireless communication network interface or adapter 3656. The adapter 3656 can facilitate wired or wireless communication to the LAN 3652, which can also include a wireless access point (AP) disposed thereon for communicating with the adapter 3656 in a wireless mode.

When used in a WAN networking environment, the computer 3602 can include a modem 3658 or can be connected to a communications server on the WAN 3654 via other means for establishing communications over the WAN 3654, such as by way of the Internet. The modem 3658, which can be internal or external and a wired or wireless device, can be connected to the system bus 3608 via the input device interface 3642. In a networked environment, program modules depicted relative to the computer 3602 or portions thereof, can be stored in the remote memory/storage device 3650. It will be appreciated that the network connections shown are example and other means of establishing a communications link between the computers can be used.

When used in either a LAN or WAN networking environment, the computer 3602 can access cloud storage systems or other network-based storage systems in addition to, or in place of, external storage devices 3616 as described above. Generally, a connection between the computer 3602 and a cloud storage system can be established over a LAN 3652 or WAN 3654 e.g., by the adapter 3656 or modem 3658, respectively. Upon connecting the computer 3602 to an associated cloud storage system, the external storage interface 3626 can, with the aid of the adapter 3656 and/or modem 3658, manage storage provided by the cloud storage system as it would other types of external storage. For instance, the external storage interface 3626 can be configured to provide access to cloud storage sources as if those sources were physically connected to the computer 3602.

The computer 3602 can be operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, store shelf, etc.), and telephone. This can include Wireless Fidelity (Wi-Fi) and BLUETOOTH® wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.
